Pretty fun game with cool ideas. Hard puzzle game! The tile-based movement was a bit clunky but I got used it after a while. A way that this annoyed me was if I had my "W" key pressed down and wanted to switch directions I would have to let go of the "W" key before pressing "A", or something. This was the most prominent issue and could be avoided by the user tapping the keys.
Great game! Graphics were very good 16x16.
