New world each time you play
Those AI's are called 'intelligence' for a reason
A homing flamethrower,
a wall-destroying graviton,
a bouncing RPG?

modern lighting engine

unless you're a cat
Believable, alive world.
So good it hurts

Will this game be available on Nintendo Switch some day? <3

Will this game be available on GOG as well?

I hope to send it over some time before release, and if they approve it, it will ;]

ok! I'll gladly buy it then! :D

ITCHIO build is outdated and will be updated soon. Most issues were resolved in steam version. Meanwhile you can try getting steam build and switch to development branch, refund if you experience these bugs.

Sincerely Ratchet, 

  The Mac Demo glitches every time I try to play the game. The intro works fine but the gameplay is not, I couldn't even play a level to figure out what the game was like. So if I did like the game, I could buy it but it glitches so how do I know if the game is worth buying. I don't what to invest my money into something that doesn't work so can you please fix it so I can at least try the game out. So do you think that you can help me,  because if so It would be appreciated?

Sincerely Ratchet103, 

That would be awesome. Thank you and keep up the good work!

Yes, new major builds will be available on itch.io and humble. Steam might see more frequent, but minor updates. Sorry to keep you waiting, but I'm hoping update will see the light of day very soon!


Hello. Sorry to bother you (again). I bought the game two years ago through the Humble store and so far, there has only been one non-Steam release. Further updates seem to have been published on Steam only, it seems. I know we who don't use steam are a minority but is there any chance that an updated version will be made available for us too? It pains me to see all those pretty GIFs yet being unable to play new builds :(
