Wow, this was incredible. This game proves that you can create genuine scares without insane monster designs so long as your pacing and your atmosphere put the player in the right headspace, and you nailed that almost perfectly. This is one of the scariest submissions I've played for this game jam, excellent work.
I will say, if it's possible to put this up on the web, I would do so. I think it gives players even less of an excuse to try it out, and this is well worth everyone's time here.
