We're very sorry for this bad experience, the game is designed to be played with a game controller, and the tutorial isn't working for a keyboard user.
You should still be able to play the game correctly though with those inputs:
|Q||Erase (if canvas is open)|
|E||Paint (if canvas is open)|
|Shift||Purify (near corruption)|
The blank screen at the beginning of the game is meant to be this way, you have to figure out on your own what to do
The experimental is well... experimental and requires a lot of processing power from the computer so it may cause some crash, we would advise you not to use it if it crashes.
Let us know if you succeeded!
The Líff Team.
