Advantages:

1. The spooks were pretty cool, I especially liked that you cut off the escape routes. Even though the player can not move, that was terrifying.

2. The pacing was cool. I love how the game manipulated the way the player looked so something would happen in the different direction. That is a nice game deisgn)

Disadvantages:

1. Maybe it would be cool to see the monster more, to see it come closer to you. Maybe it would be awesome if there was a spook involving your blanket (like something under it like in the old Grudge).

2. It was really strange that all this stuff happens and the main character just tries to fall asleep again and again. No panic, no second thoughts, no screams. Maybe you can consider explaining the lore a bit more at the start, for example you could use the sleep paralysis concept making the player hide from spooks by closing their eyes or something like that.

Overall:

Enjoyed that a lot! It gave me good bit of spooks so I am happy) Still, I think the whole concept is a bit weird and unexplained that is why I rate the game 4/5 for creativity but 5/5 for gameplay because it was good. The game has so much potential! I would like to see more projects from you and I hope my rating will help you in your jams!

Hope my feedback was useful!
