Really nice art and idea for the game, but I would say up the pace a bit, 25% every 50 points is a little slow and I was unsure if there was a win state or just endlessly looping, I think a good thing to add would be winning after a certain amount of points with an indicator so the player knows and wants to keep going. Overall though, this is a really fun and pretty well executed game idea with great art, great job! :D
