The only problem with this game is that it is really hard, one can debate whether that is a good thing or not, sure, but I ended up getting frustrated after the first two difficulties and stopped playing. Apart from that it is a game with a cool concept I just wish you would make the textures look nicer. Sure you can say: "What's the point?", I think a lot of people would agree that having some textures following a theme is a nice thing that can only contribute to your game. As a side note, the full screen mode is blurry.
