Yeah personally, other than the lag and mouse moving it seems great! I had this same issue with the indie horror game Rojo, but the game had an option to tune down the sensitivity. I would add that and maybe make it a little longer. My fav type of scare and eerieness, is creepy things have a build up. Like first you hear noises, then maybe like a door being closed then you come back its open. Maybe someone staring at your behind in the mirror. Stuff like that really gives me goosebumps! I would love to make a game like this but I don't have the skill or know how. Lixian if you see these comments, it appears like an outstanding short horror game, but please fix the tracking and add a few more spooks! It looks awesome! I'm sorry man, not trying to be a downer or anything, but just giving advice.
