Really cool game! This is exactly the genre I love and the theme is a very good idea. Also, it is not too hard or too easy. The controls work really well (even if I had to get used to jumping with W instead of the spacebar). Also, you polished the game very well. E.g. I really appreciated the invincability after I took a hit or after using my power. The art, music and sound effects are all very good! I got around 25000 points.
