I think its buggy because when i press space infront of those doors, it does nothing. It just turns on the flash light if its off and if the flash light is turned on previously it just remains on. It doesnt hide you .
We didn't have time to actually create a hide animation for the player, which is why only the flashlight changes! In terms of actually making the player invisible to the monster, it should work, assuming it isn't already chasing you down, in which case you have to make it into a subway to escape!
