The pixel art is great and the animations look good. The music and sound effects really give it a good game feel. I think something is wrong though as the game seems like it was running like at like 10x speed. All of the animations and movement were really sped up. Also I couldn't seem to continue to the next level. After I beat the boss, an arrow came up, but I couldn't figure out how to move to the next stage. I tried all the directions, c, enter, space, etc.
