Super cool. The moving inputs seems a bit clumsy and inconsistent, like sometimes I could get the player to move quickly, but mostly "spamming" forward doesn't do a thing to move you faster. Maybe I was missing something?
It's a bit like those dance games in that timing is important. Admittedly hinting of the perfect moment to hit a key could be improved. The pitch of the plop tells you how well your timing was.
Technically speaking you need to press a key just before you reach the center of a square.
