I was able to play and found that if this could've been in the oven a little bit longer you'd have a great game on your hands, I'd love to play the finished build when it comes out.
I think the atmosphere is the immediate thing that hits you and with some music this could be a really depressing scenario your in (in a good way),
The other thing that was already mentioned was that without a tutorial in some way or another, it almost feels intentionally vague on what is even going on. Which i feel like is a theme that doesn't entirely have to be dropped, it adds a bit of mystery to the game.
