Yo, that's a nice sidescroller game there, the only aspects I would probably implement were music at the menu and in-game, but it's still great. By the way, maybe you could fix the rng when the game spawns mushrooms on the way? Sometimes there's like, 2 in a row, I just don't think a player is supposed to pass those, or else the game would get boring because you depend on luck. Looking forward to it!
