Love the music and style, they work well together.
I did have some trouble getting the timing right for certain jumps, and trying to go fast, but other than that its a cool 2D platformer.
Do feel like the art style is not 100% on consistent, cant put my finger on it, maybe the outlines being to thick? Dunno, i'm not an artist xD
Also the camera snaps pretty hard when going from moving left to moving to the right.
But love the idea, the style, and music, well done :D
