Hello!
Really great game!! Just felt very chill, yet I constantly had to look over my shoulder because in reality, I was freaking out! XD
I don't want to spoil everything for other commenters, but I loved the part with the rocks and the falling animation. Plus, the design of the demon is spooky, I like it!
If you have any extra time, I made a Letsplay of this game! I'd love if you'd check it out!
Keep up the awesome work, this specific art style really works for you! :)
One quick suggestion, I think adding a blood-curdling scream when the demon flies at you, will add a TON to the jumpscare level! Maybe have the scream start when the player is turned away from it, so it startles them more!
