Why is the screen so big? Even when the game is in full screen mode, it doesn't fit - there are scroll bars on both axis. The counter at the top is almost completely cut off in windowed mode. You have been making games on itch.io for years. You should know what dimensions are good for it by now. The default viewport dimensions are 640 * 360, or a 16:9 ratio.
Your art is cute as always, and you've created a world that is fun to explore. Controlling a snot is easy. I like the high jumping. The music is playful and adorable. If the game fit on my screen, it would be perfect.
