I participated in Ludum Dare 37 and made a puzzle game where you have to keep your hotel guests from killing each other. You can play it in-browser here.
This is neat. Definitely worth playing for a bit.
Learning and remembering all of the movement patterns can be a bit tricky. I also never felt like I really fully grasped how noise / disturbances worked. Only once did Ms. Marsh do her thing fully even though I never made any formal attempt to stop her.
I did manage to have a 6 survivor night, although that's as much luck as skill.
