Actually a really cool idea! Some notes from my playthrough:
* I didn't realize the level select screen was a level select screen
* I accidentally jumped to the last level, where it said to press space to continue, but that didn't do anything so I had to restart the game
* I was really struggling with the game until I realized how important slowing down time is if you want to rotate the screen.
* The camera following the player's rotation caused a lot of motion sickness. I think orienting it to the 8 / P rotation would work a bit better.
