Found a game-breaking glitch. At the second guard, if you hide behind the second crate, he catches you and at the reset, you start behind that crate and can do nothing. You have to exit the game.
ÓvÒ/ And thank you for bringing this to my attention. I won't be able to patch this as we are all now in the judging period of the contest but as soon as it I am able, I will try to patch this.
