Game crashed in the circular room after the controls went wonky and my guy wouldn't stop moving in random directions. Up to that point there were minor graphical errors, I was able to electrocute to guards that I shouldn't have been able to, they were adjacent while one was looking down and the other was looking to the right.
Another guard was looking directly at me but the arrow was pointing another direction so I wasn't seen.
Knowing about the spacebar takeout would have been a lot more useful to know the first time lockers are introduced, as I would see the red outline but didn't know what it was for.
Overall though it looks like a decent game, I was genuinely having fun sneaking past all the guards without having to shoot them down. The electric takeout diminishes this somewhat, but I still liked it.
