Hey!
First of all, really great game. I love the atmosphere and the visuals. The fact that you made a 3D game in one week is amazing.
If you want some feedback here's mine: I think some music will be great to really sell the experience to the player, or better said, to improve it. The door SFX when you try to open it was really loud, so it will be great to make some more audio mixing. But other than that, this was a really solid game.
Congrats on making it, it's a really nice and well done game!
