Inertia, developed and published by ASTXRIAL Works, is a first-person free-running platformer that builds its entire identity around movement mastery. Rather than relying on story, combat, or cinematic spectacle, it focuses almost exclusively on speed, precision, and the satisfaction of chaining together fluid parkour mechanics. From the moment players step into its minimalist environments, it becomes clear that the game is designed as a skill-based challenge, one where success depends on understanding momentum, timing jumps perfectly, and navigating increasingly complex level layouts with confidence.
The core gameplay revolves around first-person traversal through a series of handcrafted stages. Players run, jump, wall-run, slide, and double jump across suspended platforms, vertical shafts, and angular corridors that demand constant forward motion. The mechanics emphasize rhythm and flow; when executed correctly, movement feels seamless and almost meditative. Early levels act as a gentle introduction, allowing players to familiarize themselves with the physics and control responsiveness. As difficulty increases, however, stages demand faster reactions and more deliberate route planning. The progression curve rewards persistence, encouraging players to refine their skills rather than simply stumble through.
One of the defining features of Inertia is its emphasis on replayability. Each level tracks completion times, and global leaderboards provide competitive motivation for players seeking to shave seconds off their personal best. This transforms the game from a simple platformer into a time-trial experience, where optimizing movement paths becomes the primary goal. The pursuit of efficiency—learning when to conserve momentum, where to cut corners, and how to chain jumps for maximum speed—becomes deeply engaging. For players who enjoy refining performance and competing against others asynchronously, this system adds substantial longevity.
The movement system itself is the game’s greatest strength and occasional weakness. When it works smoothly, there is a strong sense of momentum that makes sprinting across platforms exhilarating. Successfully completing a complex sequence without hesitation can feel immensely satisfying. However, the precision required in later levels can sometimes expose small inconsistencies in handling. Slight miscalculations in jump timing or wall-run activation can result in repeated falls, which may frustrate some players. That said, much of the challenge stems from skill development rather than unfair design, and mastery comes with practice.
Visually, Inertia adopts a clean and minimalist aesthetic. Built using Unreal Engine, its environments are composed of geometric shapes and stark lighting that prioritize clarity over decoration. This stripped-down presentation keeps the focus firmly on navigation and movement rather than environmental storytelling. The simplicity also ensures that visual noise does not interfere with precision platforming. Sound design follows a similar philosophy: understated audio cues support the sense of motion without overwhelming the experience. The absence of excessive audiovisual elements reinforces the game’s identity as a pure gameplay challenge.
An important addition to Inertia’s value is its level editor and Steam Workshop integration. Players can create their own custom stages and share them with the community, significantly extending the lifespan of the game. This feature fosters creativity and keeps content fresh, as community-designed levels often experiment with unique layouts and inventive challenges. For players who exhaust the main campaign, user-generated stages provide new opportunities to test and refine their movement skills.
Ultimately, Inertia is a focused and uncompromising platformer that understands exactly what it wants to deliver. It does not attempt to broaden its appeal through narrative depth or varied mechanics. Instead, it commits to offering a streamlined, movement-driven experience that rewards dedication and improvement. For fans of speedrunning, parkour-inspired gameplay, and skill-based challenges, it offers a satisfying and competitive environment. Those seeking a story-driven adventure or diverse gameplay systems may find it sparse, but for players who value precision and mastery above all else, Inertia stands as a solid and engaging indie title that thrives on the simple joy of motion perfected.
Rating: 8/10
i refunded the game after trying to wallrun and quit
I want gloves.
Goog game great for when you are bored or understimulated :D
Brilliant game, I love it, you can even design your own levels in this game.
Fun obby with good lighting and graphics.
Трудно передать насколько был рад услышать брейккор в трейлере на странице. Невозможно описать как был разочарован реальным игровым саундтреком. Не подобрать слов с какой гримасой проходил отдельные уровни (＃＞＜)
Idk if it's just me, but the sprint key wouldn't work
good game bad wallrun imo, uhhh pretty fun when you get used to it. i didnt gonna try the other game from the devs now
God
Great visuals, smooth transitions and some complex movement. Good game.
Довольно залипательно) на пару вечеров для 100% прохождения
Why? Just why? Looks fun, executes poorly.
well worth the 1 buck for sure got through a handful of levels and looked at leader board. sad too see leader board is just loser glitcher virgins :/. other then that great music had me trying tro run the levels as fast as i could right out the gate. will definitely play more later.
This game is amazing. Very fun, good levels, interesting mechanics, and amazing momentum based parkour. This game also has beautiful level design which i felt was so important it deserved its own sentence.
The movement is pretty fluid once you get used to it
juanjo q juego de mierda q me regalaste dios
PARKOUR!
Wallslides are hard to master.
Feet would actually help with the precision.
Overall great game.
Great game, addicting, amazing graphics.
不好。
newtons first law of gravity or something idk
Un juego de parkour muy simple pero divertido, esta bueno para jugarlo mientras haces otra cosa como escuchar musica o estar en un chat con amigos

Vale totalmente la pena, plataformero con las 3B.
Bueno, bonito y barato.
"I get it now" game
OK já entendi, eu sou horrível nisso.
Inertia
Rozgrywka – 7/10
Inertia oferuje ciekawe mechaniki związane z grawitacją, w których gracze manipulują nią, by przemieszczać się przez różne poziomy. Choć wciągająca, może być frustrująca przy trudniejszych etapach.
Grafika i oprawa audiowizualna – 7/10
Grafika jest prosta, ale efekty wizualne związane z grawitacją robią dobre wrażenie. Muzyka i dźwięki są w porządku, ale nie wyróżniają się na tle innych gier platformowych.
Regrywalność – 6/10
Pomimo ciekawej mechaniki, gra może szybko stać się monotonna. Brak większej różnorodności w poziomach sprawia, że po przejściu gry nie ma wielu powodów, by do niej wracać.
Podsumowanie – 6.5/10
Inertia to gra z interesującą mechaniką grawitacyjną, ale brak jej głębi i różnorodności. Dobrze sprawdza się na krótkie sesje, ale może stracić na świeżości.

RTX parkour a bit slow but works
I'm the target audience
Super fun, addicting, and visually pleasing, even though it’s quite simple in terms of graphics. I recently tried it on the Steam Deck, and it works perfectly. The only thing to note is that in the menu, you’ll need to use touch controls since the mouse cursor is invisible. You’ll have to rely on the menu items becoming highlighted to know where the cursor is. However, once in-game, everything works as expected.

Super fun, addicting, and pretty to look at, even though it is quite simple, graphically. Also, just tried on steam deck, it works. When in menu you need to use touch. The mouse cursor can be used but it is invisible. So you have to rely on menu items becoming highlighted in order for you to know where the cursor is. In game it works as you would expect. Full controller support.
ta weno pa cuando no sabes que jugar y te aburres
I'm sorry there's no Russian language, but the game has come to me!
This game is very very bad. The worst part is the movement. It is broken, laggy, and just not well done. The lvl desighn also lacks a lot, and the music is strange. Dont reccomend to buy
Нервы потрепать можно, но для меня эта игра слегка не проходимая, застряла на 11 уровне, и вышла нафиг с удивлением, что уровни, которые я прошла не сохранились и было все стёрто с 1 уровня, обидно конечно, но по задирать можно, рекомендую игру.
gameplay is solid and doesn't feel polished or smooth
玩法简单动作流畅，如果再加上背景剧情的框架那将是绝杀！
Horrid movement
bad movement
Inertia attempts to deliver a fast-paced, physics-driven platformer experience, but it has several flaws that detract from its core appeal. Here’s a breakdown of my thoughts after spending some time with the game.
[b]Gameplay and Mechanics[/b]
While the game’s design relies heavily on mastering momentum and timing, the controls feel clunky and unresponsive. Precision is crucial in a game like this, but the frustrating controls make it difficult to execute precise movements, especially in higher-difficulty levels. This significantly impacts the enjoyment factor, turning what should be a challenging experience into one that’s often just irritating.
[b]Levels and Visuals[/b]
Inertia has a minimalist visual style, relying mainly on geometric shapes and simple environments. Unfortunately, the game puts an unexpected load on the GPU, causing performance issues on systems where it should run smoothly. Given its minimalistic graphics, this lack of optimization feels out of place and detracts from the overall experience.
[b]Conclusion[/b]
Despite its potential as a high-speed platformer, Inertia falls short due to poor controls and a surprisingly heavy load on the GPU for such a visually simple game. It’s difficult to fully enjoy the speedrunning elements and momentum mechanics when the basics don’t feel polished or responsive. For now, it’s an experience best suited to those who don’t mind working around these issues.
[h1]My Rating: 5/10[/h1] – a platformer with potential, held back by performance and control issues.
boring and over hyped, but its cheep and if it scratches an itch of yours, then its wtv
Inertia is a physics-based platformer that offers a thrilling challenge for fans of fast-paced, precision gameplay. The core mechanics revolve around manipulating gravity, allowing you to pull off exhilarating jumps, glides, and wall slides through a series of increasingly difficult levels. The minimalist design works well, keeping the focus on the tight, responsive controls and the obstacles ahead.
While the difficulty ramps up quickly, it never feels unfair—every failure is a learning experience, and the sense of accomplishment when you finally beat a tough level is immensely satisfying. For those who love mastering tricky platformers, Inertia delivers an intense yet rewarding experience, making every second spent honing your skills feel worthwhile. If you're looking for a game that challenges your reflexes and persistence, Inertia will keep you on your toes.
in my 8 minutes of gameplay before i rage quit, i got that its a good game with bunny hopping and momentum jumps, overall good parkour game

Whoever made Inertia's soundtrack was COOKING
I'm an object in motion, I've lost all emotion
funny
For a 1$ this game is super worth it a really good game better then some 80$ games just buy it its super fun
controls are sometimes quite delayed and frustrating but this is an excellent 3d platformer at just 75c aud
perse haisee ja silleee
жопой вытираю пол соседки
sympa bien que je sois nulle je mamuse quand même
good game and cheap
기본기를 조합하여 스킬을 써야함 머리 좋아야함 운빨도 있지만 실력이 70퍼 차지함 진짜 손 발 땀 장난아님

Good, relaxing game with nice music.

I HATE INERTIA...
SO SLIPPY
god
It's a game, not a bad one either...
32+10+6 Levels. Awesome speed-run parkour game can be beat in three hours worth my dollar. There is a wall running that takes weird chance to work with boost pads but double jump and run on the walls you'll get it working and turn of strafe jump seems to fix my issue.

本来看宣传片还以为是能玩得很爽的类型，结果玩了一会问题非常大。
整个游戏的逻辑是难以自洽的，如果是不追求速度只想通关，那么关卡给的平台属实太少，太容易摔死，并且很多关卡是对速度有要求的，想慢下来还不行。如果是像我一样没法做到最快就宁愿不过关，那么整体的操作手感和反馈又太差，滑铲经常失灵，操作时机差一点点带来的差距也非常大，稳定性很差，给人感觉极其便秘。
第一关我也花了点时间打了个记录7.85秒，但这个记录完全没让我有什么成就感，因为我感觉只是运气好了点，按的时机比较恰当，完全没有觉得自己掌握了很复杂的技巧。一个理想的跑酷竞速游戏应该是新手上来能慢慢摸索过关，熟悉关卡之后可以反复凹操作提时间，在这个过程中提升技巧熟练度，而不是一上来就面临着不能死亡和不能慢下来的双重考验，还要忍受手感的不流畅，直到随机打出一次自己也看不明白的操作过关，甚至最后时间可能还挺快。
简而言之就是游戏机制本身挺有潜力，但是关卡和操作设计属实拉了大胯。
very cool for potato PC and chill 8/10
A really entertaining run and jump puzzle, that will teach you the true meaning of trial and error.
Very good platformer sandbox, but that's all it is
fun
Graphics are amazing.
Gameplay is satisfying.
easy for learning BHOP mechanics
cheap
could probably run on a calculator at high frame rate
well designed levels
only one complaint... lacking features
ну норм
Platinei o jogo.
Jogo bonzinho e meio desafiador as vezes, como todo jogo de parkour é.
Se vc curte jogos de parkour, vai gostar, não tem muito segredo!
手感很怪，但是熟练了之后其实还行

♥♥♥♥ THIS GAME
Great.
A pretty simple Parkour game. Very fun to slide around and break the game though, but the game is still polished and fun.
big recommendation!
it's a movement surf game
very good for a relaxing evening
already love it
even has workshop support
Its really good and calming! Please make a second game.
The mechanics are nice. It's a good deal.
I have been loking for like two year for a polished parkour game. And only on 2023-11-25 I found Inertia. I mean its just amaizing its fast its fun its relaxing and also difficult at the same time. And to all the peopole that dont have it buy it now its so cheap and fun(thank me later)
손풀기
Inertia is a 3D rendered Unreal based first person platformer, and another one of those games where the review is somewhat more difficult to write, because there's a lot going for this game and a few things going against it. However, Valve does not provide a "maybe" option for reviews.
The game has you running along some incredibly bland and dry sterile neon arenas, performing double jumps and wall running, avoiding hazards, jumping on the right platforms and using various mechanisms like teleporters, jump pads and elevators to get to the end of the level as quickly as possible.
There's also a level creator mode which is a big plus.
There's also some unfortunate drawbacks.
From a technical perspective, the game doesn't meet basic minimum requirements that most PC gamers expect as standard.
The game features lazy minimalist low-polygon "retro" assets and visuals, making this look like a barely functional 3D game from the early 1990s. The primitive handful of just 1-2 grey textures plastered over every surface is a method that lazy devs often use to disguise their lack of talent/interest in doing the graphics properly and trying to disguise it under the name of "art", or "We made it look bad on purpose", which really isn't something gamers should have to put up with. I know the game seems to be trying to ape the look of games like QUBE and Portal, but in this case it just comes across as lazy.
It's unclear why the developers weren't willing to arrange high quality, high polygon count contemporary assets and high resolution textures for the game. It looks bad as a result of their decisions, and that's a reason to avoid it.
However, visuals aside (and while they are bad and lazy, they're also well polished, in fairness, thanks to the venerable Unreal engine) the real killer here is the awkward controls. It just doesn't "feel" good to play... the handling is off. You jank a lot when wall running and you can fall for no apparent reason. Jumping and sliding seems unpredictable and sluggish... With games like platformers, the game control handling and "feel" has to be absolutley perfect, and in the case of Inertia, it isn't. That's a killer.
These technical defects push this game below acceptable standards for any modern PC game.
The poor quality of this game is reflected by how many people spent time with it. At the time of this review, SteamDB shows the all-time peak player number was only 18 players. This is a remarkably low number, and now, the only player activity occurs once or twice a month, presumably someone loading it up to see what it is then quickly uninstalling it. Considering there's over 120 million gamers on Steam and well over 50,000 games for gamers to choose from (over 9,000 completely free titles), the overwhelming lack of interest in this low quality game is to be expected.
Inertia is relatively cheap at $1 USD, which is the primary reason I'd give this a "maybe" if I could. However, I think gamers looking for this kind of experience might enjoy SEUT, QUBE or Portal instead, which aren't much more expensive games and offer a higher quality experience.
Very fun and interesting parkour game. Very deep movement system I have never seen before. Each level is well designed and not repetitive. The levels keep the game very fun and interesting.
A simple Platforming game with good graphics. 7/10
god juego de run y parkour con un estilo unico
HOW IS THIS GAME SO AMAZING LIKE SO CHEAP AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHh!!!
Bu oyunu 1 ay önce istek listeme ekledim. Fragmanını görünce heyecanlanıp almak istedim ancak alamamıştım, steam mağazası hata vermişti. Mena Usd haberi gelmişken bir baktım, bu oyunun indirimde olduğunu gördüm. Bir şans vermek istedim oyunu (5,50 TL'ye aldım) ve denedim.
38 Dakika boyunca oynamışım. Oyun çok güzel, bağımsız yapımcı. Hatta bu ilk yaptığı parkur oyunu ve başarılı. Sinirlenmedim, oldukça kolay. Bölümler gittikçe zorlaşıyor, zamanı geldiğinde de yeni mekanikler ekleniyor (Kayma ve Duvara koşup atlama gibi) Mantığını kavradıkça speedrun deneyebiliyorsunuz. Ayrıca; mekan düzenlemeleri ve grafik kalitesini beğendim. Puanım: 10/8
Hem ucuz, hemde mekanikleri çok hoş.
Bad physics. Waste of my 1.29$
3C欠打磨，导致手感等各方面达不到预期，第一人称跑酷啥都沒调教就端出来了，不太好吧
36 minutes or so of not-that-great platforming, still worth the 99 cents
very cool parkour game for parkour game lovers
