Haunting your own house is an interesting game concept. Most of the sound effects and graphics were good. The ending was unexpected.
Just some things that might be looked into:
Need a way to pause and make it easier to adjust the gamma in game.
I had a lot of difficulty interacting with some objects for some reason. Only worked after reinstalling the game.
The scares could use some polishing. The creepy girl and generic scary little girl music jumpscare was a little cheesy. And having two of them back to back even more so. The game probably could've worked well without them. The writing on the walls and the ending may have been sufficient I think.
