Nice cute idea! Pixel art is cute too, but I'd add some background not a single color, and next time export to html instead to windows, because you will get more ratings. Not everyone wants to download game because it could be a virus.
Thank you for playing and for your feedback ! I'll add a background on a post-jam version.
I tried to add HTML version but the sounds didn't work correctly. I'll try to fix it for my next jam.
