Great idea for a game, but there were some flaws which really bugged me:
1. invisibility is useless--the guards just stand there and look at you untill you're visible again
2. sometimes they can see me through thinner walls--thin beams of their vision would occasionally pierce through the wall
other then that it was pretty good as well as addicting
