A downloadable game for Windows, macOS, and Linux

Download NowName your own price

You play a shrinking scientist in a race against time: Can you find all necessary formulas and ingredients to produce the antidote and stop shrinking, before you are too small to operate the life-saving lab equipment?

Processing ingredients takes valuable time – time you should use to search for missing components or rearrange the lab for when you may be too small to reach the machines you need!


Search for the formulas and ingredients you need to produce the three key components of the antidote!

Each formula corresponds to one of the machines in the lab. They produce new ingredients, which may be used in other formulas or are one of the three key ingredients you are looking for.

To win, collect all three key ingredients and place them inside the antidote processor.

When you shrink too small the game is over!

My mouse in-game goes up without me doing it, it looks up towards the ceiling and I can't control it. Has this happened to someone else?

Sorry to hear that!
I think we've had similar issues like this in the past – do you maybe also have a game controller connected, by any chance? If so, you could try to disconnect it before starting the game and see if the problem still occurs.

Yea I had a controller in, unplugged it and the mouse and restarted. After all was good ^^ GREAT game btw :)))

Ah, sweet! And thank you! :D

I have been trying to launch this game for days now and can't seem to find out how to do it. I am trying to launch this game on Linux, my computer is an Acer Chromebook Spin 11. Can anyone help me? The Itch.io app also won't start up, it just loads on forever.

I thought this game was so so good. I've been playing it the past two days and had to make a video on it.



This was a really cool game!

uhh i know, im late here, but i think it's my videoboard, but the game colors are so, idk, like texture errors? sounds like the game itself, bc i tested in the gaming pc of my friend and same, some solution? or my pc trash and he got an possesed pc?

Oof, I think I saw a similar issue on an old notebook one, which is why also assumed it was a problem with the graphics card, or some such... But that doesn't explain why you had issues on the other PC, as well. 

Have you tried turning of "Post FX" in the graphics setting? Those sometimes cause problems, but otherwise I'd have to look further into it!

oh sorry, it was my graphics card, thx anyway, but in the other pc, it was the post FX, very cool game bro!

Really interesting game!



WOOOOOOOOW, its a good game. and funny to play!!!!!!!

Thank You!!!

Good game, good models. I loved it, it has humor, it had a challenge. Mixing random ingridients to get a potion to start growing, is funny and pleasing to play.

Inch by Inch not running on Linux if you use wine

Sorry to hear! What distro do you use?

originally Wine and PopOs but i fixed it by using itch

have you tried beer?

Nice pun


This game is great! I saw my fav youtuber DanTDM play this game so I wanted to try it out and I am started to liking it. Keep up the good work!

Great game! Have you considered making it vr compatible? I think it would work great with roomscale and a teleportation mechanic that changes effectiveness relative to you size...

Glad you like it! :)
And we definitely have considered it! At the moment there are no concrete plans to port it to VR, however; mostly because we curently lack the necessary equipment and making it VR compatible would require large rewrites of the entire game, unfortunately - but we'll definitely keep it in mind!


amazing game

Are you now making it into a full game with Size Matters or did someone steal your idea?

Hi, there! Size Matters is a separate game that has taken a lot of inspiration from Inch by Inch; here's a thread about the situation, over at: Steam: https://steamcommunity.com/app/992120/discussions/0/1741103267312288922/

Couple Suggestions:

1) Maybe have a couple of maps to choose from. It would be nice to change up the room.

2) Maybe have a list of names for the potions that players can change so they can have their own potion names. Ex: Vividiom (not the best namer)

3) It almost seems kind of sad being in the room because it is so grey. Maybe liven up the room a bit.

How long does it take with a shrinking factor of 1 to get to the end height?

Oof... if my math isn't off it's like ~11 minutes, I think?

is there other potions you can make

besides ????? and the keys?

Only the ones from the formulas to create the key ingredients, I'm afraid!

("?????" is just a stand in for anything that is an unknown/undesired result)


The game play very laggy in my i5 with drivers installed and up to date with low quality.

Sorry to hear that! Have you also tried deactivating all of the post-processing effects?

Yep, all Graphic setting off and low. Still laggy :(

try put it on low in main settings then go to advanced and press the preset and click the off preset

Is there a reason the Mac version is available here but not on steam? I bought the game on steam but had to come here to play on Mac

No particularly good reasons, tbh. For the most part, the Mac version is less tested and makes up a much smaller market share. 

We can definitely think about uploading a macOS version with the next update, over on Steam! Sorry for the inconvenience!

It says "The code execution cannot proceed because UnityPlayer.dll was not found. Reinstalling the program may fix the problem."

Hi! In the same folder as the executable there should be that UnityPlayer.dll file; the exe and dll file need to stick together, otherwise running the exe won't work. If that file is missing, it has either been moved or removed (possibly by anti-virus software?)

Loved this game! We played it on our Youtube Channel, Catatonic TV!

Interesting idea! The pacing is a little frantic but I was able to beat easy mode after a few tries, then "Scientist". The controls for grabbing and placing objects are a little awkward, but that's a limitation of non-VR controls.

Amazing, I loved every second of it.

Interesting little game with a unique concept.

very nice little unique game

Super fun game! It is amazingly difficult for an indie game. Thanks to the creators

Good game!

What a unique and awesome concept! I loved it! 5 stars!


Nice game, really fun to play for me

Is this available for x86 linux systems?

Sorry, I'm afraid there is no x86 Linux build of the game. .. 😔

Thanks for the reply!

very great game I had alot of fun playing it 

Super fun game. Puts the pressure on you that's for sure!

I really enjoyed this one! The design was clever and the minimalist look made me feel like a real scientist lol

How do I actually play the game with my windows 7 computer

Mhh, as far as I know, the game should be compatible with Windows 7 – have you tried both, the 64bit and the 32bit version?



If you guys develop this further, a vr version would be very good and immersive 

As much 'fun' as VR would be with this, the distance to go from one side to the other gets very long.  The jumping and running that takes place would become likely vomit inducing.  Another version of this game would be very interesting (based around standing in a more confined area).  However I'm not sure how well a VR adaption of this would do in terms of just not making people sick as it is set up now.

I think using a teleportation mechanic like The Lab, Budget Cuts, Talos Principle etc. would be the way to go - just limit the distance you can travel with a 'jump' teleport as some constant * your height. It doesn't need an in-world explanation, I think - teleportation is just the bog-standard VR movement mechanic 🙂

I only just got a VR setup and even so a couple days ago I was like "I'm sure there was this time-limited VR puzzle game where you got smaller and smaller and had to mix up chemicals, where is it in my steam library?".. hah! Your game must be pretty good if I thought I'd already played it in VR!


Love the sounds in this game :)

I LOVE this game. I like the aesthetics and the challenge. I'm okay with there only being one map, but maybe randomize the objects along with the other things? That's all I got .
