Pros and cons are down below) Check my vid here (the game is the 2d there, likes and subs are highly appreciated!):
Advantages:
Though, the concept of sleep paralysis is not new, the scares were pretty fresh. I didn't expect them and I think that's a big advantage for the game. I loved sound design as well, the knocking seemed realistic and very creepy!
Disadvantages:
The opening or closing the eyes didn't matter at all, except for the window moment. I think that the game would benefit a lot from making the player close the eyes from time to time. I mean, the last jumpscare could even be missed because of closed eyes. I think the game requires a bit more work and polish.
Overall:
I think that the game needs more polish) I feel that it was promising but the whole opening and closing eyes concept being "just there for no reason" kinda ruined the ambiance. I think that the game would benefit a lot from a more complicated opening/closing the eyes mechanic. Like in the game called Try to fall asleep. That game made it crucial for the player to keep their eyes closed as long as possible. Here it didn't really matter. I think that if you'd came up with a good reason for closing / opening the eyes the game would benefit a lot from that. As is, I'd rate this experience 4/5 stars. Still, I think it's promising and I can't wait to see more.
Hope my feedback was useful!
