The polish is nearly perfect, it's just missing the transition part between level, everything else is perfect.
The idea is not so creative, but one more time, the game feels different than the others because you added your own twist. So it's not just like the other game, it has an atmosphere feeling/a different to see the puzzles. The base idea is not the only thing to take into account in the creative part imo.
It could have been really nice that the doors serv as checkpoints, but checkpoints are sometimes hard to make in a jam haha.
The puzzles weren't too hard for my brain, so thanks and well done :D.
