I like the concept of the game, very cool interpretation of the theme.
The delicate controls are holding the game back however. I often found my self doing a 180° when I just wanted to do a 90° turn or moved far further then I intended to. The perspective could need some work too, I cant see the tile I am standing on, nor if there are walls to left/right from me. The frame rate is okay but could be better.
Other then that its a solid game with interesting ideas. Aside from the haywire controls I had fun, what more can you ask for?
