Nice game. Specially like that you used a comic format to present a storyline.
The controls are kinda slippery (but I think that was the idea).
The theme is more on the story than on the game mechanics (which may be good enough).
Sometimes, since the player is a cube with no face, eyes... I lost the sense of direction, and I didn't knew in which direction the sword was swinging. (Those deaths were a bit frustrating).
