Exceptional polish! The animations, the character design, the lighting, it's all above what is expected of such a short jam. The gameplay is, by and large, great as well. I have two problems: the monsters not being visible when not lit is a great choice, of course, but do make sure not to cheap out the players with it. After the first breakroom, there is a monster hiding around the corner and, when a player approaches, it will not be naturally lit by their flashlight. You sort of just need to know that it's there. Secondly, I'm afraid that hiding was a bit inconsistent for me. I understand you get hit when the animation is still underway, but I've also gotten hit after the animation had already finished and the box had been settled for a few moments. This made me avoid using the hiding mechanic, which is, of course, supposed to be an important mechanic for the game.
These were really my only problems with the game. It's very impressive, how much you managed to achieve in such a short time.
