I really love this game! It has art, music, gameplay all packed into one! I'm not sure how you even made that in 2 days.
Anyway, One (or two) things I don't like is how there's no option to use left and arrow buttons. This made the game nearly unplayable for me because I'm a loser who uses arrow keys xD, now for the gameplay, I'd argue it's a bit too hard, but I'm probably biased because I'm not a platformer guy.
Good Game Overall! Keep it up, you rock :)
