I like main graphic in this game. The music make me feeling like I am on adventure it is nice :D I like die animation it looks funny but after die, you must wait to long time to respawn. Maybe you should add some checkpoints. Also, in a game like this, it is good to have more than one way to go to a destination. If player respawn, it was I think better if music was independent of main scene. So when player lost music can not start from begin but be continued :) Movement is clear and respond on time. Oh I think you can also add some text on the beginning of level something like "WASD/ Arrow" to move and "You can make double jump" Nice job :)
