I like the horror on this game, it creates very strong tension with how the maps change out, going from a consistent white to the backrooms altough the last level does look quite out of place, I like the game going from a fully lit room to a dark room.
In the dark hallways sequence it would have been way more effective if the monster was not shown to the player, let their imagination take over, and the monster being a fully black Tpose monster kind of breaks immersion so it would have been way better to keep the screams but not the monster, leave it to the imagination of the player.
In the tight maze level you get stuck to the walls, in unity you would have to make a new physics material and apply it to the player with the friction of 0, in any other case you just get stuck upon a contat with a collider. Also in unity you can add post processing effect called tonemapping, in the maze level the flaslight is dim but gets hilariously light when you get up close to a wall which would be solved by tonemapping. Also there are some camera issues that made it a bit harder to solve the little pin puzzle.
I really like the screaming sound effects, they got a good scare out of me even though they felt a little cheap at times and.
The music and the atmosphere is quite good and I see alot of potentional with your skills, just have to keep some elements more hidden from the player and let their imagination take over for the scary parts. Good game :D
