Okay, I was pretty excited for this one, I'm not gonna lie.
I didn't get terribly far (until the yellow room, where I died). I had to unplug my second monitor though or the game was almost unplayable because the mouse would not stick to the game window. If you make first person games, be sure to use: Cursor.visible = false and Cursor.lockState = CursorLockMode.Locked. This will make sure the mouse sticks to the center of the screen and not be visible, which is ideal for a first person game.
Something I got confused over was that I needed to crouch to pick up the first keycard on the floor. There's no real feedback to the player as to if/when they can or can't pick something up, so I had no idea and struggled for the first few minutes.
Also, I really don't know what a 'locker' looks like in this game. I didn't see one but maybe that's just me. I didn't understand the monster's AI, whether I keep my flashlight off and crouch in a corner, it always seems to find me.
What's more is that the monster seems to teleport? I came out of the blue door into the room with the blue hiding curtains, knowing the enemy was coming from the blue door's side. Yet, suddenly, he was apparently in this dead-end blue curtain room behind me. Unless maybe he came through the purple door.. but it was baffling to experience.
The voice acting was a nice touch and I appreciated the explanation at the start, but I feel like it needs more work for the game itself to actually be a fun to play horror game.
Mind you, there seems to be a lot of content for a jam game and I'm impressed.
Edit: I see that some of my points were already answered in the post below, so sorry if I re-addressed some of the same issues.
