It’s truly an amazing mechanic, and the story fits the mechanic perfectly. I hope you can give the full version a really satisfying ending.
As for the gameplay, I’d like to suggest something: when the player turns their head to the side and keeps looking toward the corner, the camera could continue rotating in that direction. You could also add a keybind for quickly turning around 180 degrees.
I think features like these would make the gameplay feel even better and more immersive.
Wishing you the best of luck with the project!
