Really good job at guiding the player the right way, after I got the pull power-up, I thought I just swapped it out, but the next room explaining it was smart. Also in the flashing room when it tells you to pause and it zooms out, I was like OMG!! What a reveal! It was some Grade-A showmanship! It was a little cumbersome to walk around the room with the point-and-click style and I did sequence break a little with being able to grab the mirror and pages sooner than expected, but including the diary and trying to understand why Delilah made the puzzles more personal than just "go up, down, than left" which a whole new layer of enjoyment from the game.
The collision was a little frustrating, some blocks looked like they could be pushed/pulled but wouldn't fit some times when I loaded into a room, and other times I got stuck along a smooth wall and had to redo the Naga room a lot. The game was super bright and hard to make some stuff out, but the minimal Atari graphics made it manageable, so great job tying the theme into functionality! Also the room getting changed via the game was a little paranormal element I wasn't expecting, maybe the player having to puzzle together that the room was the same as the one you're in and having to manually move the bed in real life could have bridged that for me, but perhaps there's an element to the story I missed with that.
I'd love to see an expansion on the parallels to understanding the developer character to solve their puzzles in-game if a continuation of the project happens or a sequel!
