It was an interesting game. The environment was well done; it was super dark and there was an air of mystery about in the setting. The background music was good and kept me at the edge of my seat towards the end of the game while expecting more jump scares.
But the house itself was very empty and the hallways were very empty and that's what made the jump scares feel sort of cheap in that manner. There was nothing to tell the player that they would have to expect one and nothing to build up to one.
Though saying that, I think that at the beginning where you added the bloody skeleton moving around and then it runs towards you was a good add on and the scariest part of the game as there was a build up to the scare and it made sense. The story was also not really there; maybe adding notes and other cult-ish things might add to the story and make more sense.
And the camera controls were sort of weird, where it didn't exactly follow the cursor and had a fixed cursor position.
The game has great bones and could be great as things are flushed out, but you did a good job on it and good luck for future updates and games!
