Fun and very atmospheric! Got everything but for some reason it wouldn't let me shoot the gun at the ghost.
I did find a bug where pressing E to pick up an object would sometimes drop the current object and sometimes let you pick up multiple stuff like the gun and the flashlight at once.
If you wanted to improve I suggest making the player either not cast a shadow or giving it a character model. It kinda took me out of the game to see the shadow of a capsule as I went around.
Overall a fun little game and a great first 3d project. Good work!
