Not bad for a first game, but it could do with more polish. The assets feel consistent, but I wouldn't describe the game as having a creepy or horror feeling.
I think there is lots of room for effects and "juice". Maybe signal to the player that a monster is following them with some kind of monster screech sound. Some way of indicating damage other than the health bar changing would be nice too. Just a couple of examples.
I tried to get away from a monster that was chasing me but it didn't seem possible to lose them. Some way of making the monsters lose the player would be good I think.
