This game is actually really good! The concept is really neat and i didn't expect a horror game for this jam, art is pretty and sounds are on point, so... for the level design tips:
-The levels are too straight, maybe add some elements to make it less point a to point b, like having to collect a key to open the door.
-The insta kill by too much noises is good, but it can limit level design because of the limited movement, maybe some levels don't need to have that and focus more on the enemy variety, maybe have one like the ghost from mario, maybe have one that goes directly at you but you use that pick up item that generates noises and it goes there instead to you.
-Hiding spots are a must have in any horror game right?
-Also a dark level with a flashlight could introduce light phobic monsters.
In the last level the player overlapped by the door, so i think there's a problem with image depths there.
Good job at finishing the game on time!
