Phenomenal! The Demo impressed me to the bones!
Now, from the start, I really did not have high expectations for this, yet I was thrilled, scared and creeped out, legit losing the ability to talk during the gameplay - masterfully done. If the demo provides and showcases what the game is going to be, then you have a banger project for sure mate.
Most of all, I was immersed in the small environment of the house, which seemed simple, nice, neat, yet something was definitely off, in a good, horror way. The interaction with the character was well done with the rest of utilities, such as sound design and ambience, including AI chase and the outside façade.
There are some minor issues, which I clearly talked about in the video with the character development and movement and doors, but overall, I can't praise this enough - it was chilling, superb.
Good luck with the project and future games mate. Cheers!
