Very cool base for a horror game, I really like the atmosphere you've created. I did jump a little at the blood geyser, I was able to find all 3 keys, and I particularly liked the way that the reflections in the window moved abnormally (it really helped add to the eeriness of everything).

I'm not quite sure that it fits the theme of the jam, maybe I missed something (I couldn't figure out if there was a way to play the tape), but definitely and interesting project!
