Needs some work, but not bad.
Overall, the idea is very good, the design of something that's in the darkness, but not existing physically is hard to accomplish, because the atmosphere needs to help it's believability. I guess, that's the main idea behind the game.
Rest if fine, I respect the self-made assets and environment, which is really neat. Although, some issues need to be fixed and most importantly the cursor, which is visible on the screen and it's not centered, I guess that needs to be fixed. Other major problem is collision with objects. Some of them, like chairs in the room have the collision, but other's don't and it looses it's value of gameplay. Definitely needs fixup.
But other wise, neat looking game, it has some potential and good luck with the future updates, if you are planning to, if not, just little fixup would improve the quality. Good Luck!
