Aha, I loved it! It recalled me of some of Breath of the Wild's shrines :D
I missed audio in general.
I found a bug: when my player was squizzed between a fixed structure and the rotating wall, it was expelled to the black external area, and couldn't get back. I rotated and it has falled down into emptiness, so I had to refresh browser :D
But apart from that, the game is really nice and fun. I want to finish it!
Nice job!
