Pretty fun game, the visual and audio effects create a pretty nice atmosphere. The aiming system is interesting, creating some type clumsiness that can cause some panic moments. I got stuck after going through a room with two monsters, maybe a bug or maybe I miss something. Anyway I enjoyed the game, it's like a mini Dead Space.
I've seen that you submitted the game to another jam also, this is your first GWJ, so you probably didn't know, but FYI for the GWJ you can't submit your game to multiple jams, from the rules on the GWJ page:
> This is an exclusive jam, meaning that entries made to both this jam and all others shall be removed unless otherwise allowed by the organizers.
