Very neat game, and the music sounds pretty good. Two small nitpicks; It'd be nice to be able to move with WASD keys as well, and sometimes I would get stuck on walls, other than that the game was really neat!
Reminds me a bit of The Legend of Zelda: Phantom Hourglass as you try to avoid the Phantom Knights, which were basically unkillable, so you'd hide in magic sand pits where they couldn't reach you.
