Hmm, I could hide and interact with the first door, but was unable to go in as the door was locked, and the guard only walks up to the second door (which is a little far away) before changing his flashlight to red and then turning around to walk towards me (he hadn't detected me because I was well out of his range, but still...)
I'd suggest having another look at the game and fixing the problems in it before putting it up for everyone to play, or at least some explanatory text in the game's page could help :)
