This is fantastic! Although each of these has been done within other mindbending games, I like how put together they form a unique puzzle in it's own right. I really enjoy the amount of polish you were able to put into a already difficult premise, and all the work you put into adding settings, sound, menus, level selection, and even a timed mode! The puzzles were pretty good, I especially liked near the end (I think level 5? 6?) I experienced a fair deal of glitchiness and lag especially during the portal rooms, but that's expected especially with the extra camera setups. Also, all of this in Godot! It's amazing how much you have been able to push out of Godot. Wonderful work, thank you for the game!
