The music is kind of cool actually, it sounds like a really old retro-type game.. The controls really confuse me so it makes it a little more difficult I think just because I'm so extremely used to arrow controls rather than wasd. I noticed if you jump and hit something just right you get a huge boost. I like the art style, music fits it quite well. Size proportion of you v enemies is a little weird; some are really small so it makes it look a little awkward. But overall, really cute and really fun :)
