I'm having problems loading the game on itch, so this is going to be based off memory from class. I love the concept, and everything being super trippy was enticing and super cool to look at. I like the sound design that you included into the game as well.
I would also definitely recommend expanding on the narrative, and making it so that you have to go through certain doors, unlock others, etc. It would help immerse the player more as I felt out of game and detached from the experience a lot of the time - making the game more than "this looks cool". Overall a super nice concept!
