Played it on my stream and enjoyed it!
I felt that it took a bit too long to get started, but then when it did it felt like it wasn't sure what kind of game it wanted to really emulate...or, more accurately, what type of horror. I don't want to give spoilers, but it jumped around a bit and made me (and my viewers) go "HUH?!"
I really hope this gets fleshed out into a full game. I really want to find out what happens and how many more genres you can cram in here XD
I will say, as a solid critique: it takes FOREVER to get started. You could completely do away with the hopsital entrance and it wouldn't affect that game at all IMO.
