On the "how to play" screen, the buttons are placed over the text, which made it hard for me to read.
When the game starts, the drawing suddenly feels offset from the brush compared to how it worked in the tutorial. I'm not sure if that's intentional?
But! Enough criticism — the game is really fun to play overall. I love the animations of the Nits, and the overall art style is super fun.
Very nicely made and definitely entertaining.
