The atmosphere is great at building tension also its great that you did some voice acting I always love that in jams but the constant jump scares kind of ruins the experience. Adding constant jump scares isn't a good idea when trying to do horror. It would startle the player for one second but thats it making the player feel like there would be a jumpscare any second is more effective. Here are some horror tricks for next time. Changing the artstyle (look at blackspace from omori). Adding things that should normally not be there. (think back to that scene with the two girls in the hallway from the shining). Turning the music off in certain scenes. Using ambient noise. Using primal human fears such as being watched. Anyways I still enjoyed this game even with it's flaws good job :)
