Cute graphics and nice sounds. However, the game is very strict with your controls. The jump stopped the instant you let go feels unnatural, but could be interesting if the game was focused on more specific jumps with tight timings. Also another good practice that most newer platformers implement is a sort of grace period when running off a ledge where your character still has the ability to jump. Just a few frames makes it feel a lot better. There were many times I tried jumping right at the ledge, but ran straight off haha. Good game though! Keep it up! Making it feel really good is one of the harder aspects, so don't be discouraged. You have a lot of potential.
