This was really cool! I love the hints over the course of the game of what the player is, I suspected fairly early and was pretty excited when I was proven right! The lore is super interesting too, I really wanna know what happened with Alice and the ahem 'pole guy' (to avoid spoilers :P)
The puzzles were interesting too, I like that you played through effectively the same puzzle a few times over, but with changes to unlock previously impossible things! :D It gave a very nice sense of progress!
I also liked that sudden moment of realisation of what the greyed out options represented. I initially thought they would be available through multiple play-throughs, but I like this version more! Definitely a bit of a gut punch (in a good way!)
Overall I really enjoyed it, and I have to say the visuals are quite nice too. My only grievance is that you couldn't open the safe early on a replay </3 (woulda loved to see them try to figure that one out lmao)
