Hey, great game, I wanted to let you know that, at least for me, it drops input on the arrow keys a lot when I'm going fast. I've gotten to the first stamps level and these are the only keys I've noticed doing it. Also, you can just hit all three stamp buttons instead of matching to the color
That said, this is really good! You've kept me playing for half an hour and iv'e thoroughly enjoyed every moment of it. Hope to see you in the next jam.
