Good use of the theme.
Camera tracking could be better. Sometimes I had to walk to the edge of the map for the camera to move, but then I cant see the enemies in the next room.
You can lock yourself in the tutorial rooms. Maybe the room where you have to shatter your weapon should unlock the next door when you shatter any weapon there. Shattering your weapon next to an enemy can knock them out of the room. Which leaves you no way of leaving the tutorial.
