I liked the graphics and the movement animations. The background music is good, I would add some sounds to the enemies.
The movement mechanics are good, but as you can't see anything, it becomes frustrating too fast and finding the mirror becomes more a question of luck than ability. Maybe having a way of switching the lights of the maze on for a second or so, so you can have a glimpse of where you should go,? Just an idea though.
Good game, congrats! :D
