Looks amazing and is fun once you understand what you need to do, a tutorial would be nice. The sound effects are good (a bit deep) but there could be a bit more for button presses etc. I think it fits the theme nicely cuz you collect the balls and the art is great, even with a matching font. I like how you took that gameboy "pixel aesthetic" and made circles out of the pixels instead.

Liked it! nice concept, well executed, very good! the only "issue" i found is the music being a bit too heavy, but that's no big deal! if you have time please try my game too, i'd love to get some feedback!
