This was pretty cool, indeed.
The pixel graphics are nice, and the music is cool, although I believe it doesn't fit the theme of the game very well.
I quite like the mechanics of the game, where we need to absorb fragments in order to acquire higher powers, and the fragments are the building blocks of different objects found in the way. The shrine battle was nice, but beating it without dying is close to impossible. The full power state lasts too short, since you spend fragments whenever you shoot.
