I really liked the atmosphere of the game, the music and the attention to small details like the door half opening in the broken station and the furniture floating, ...
It is confusing to have access to the different puzzles but have no indication of which ones I can or cannot use... I found the code first so I tough yeah, let's try that but couldn't figure out why I couldn't type it. I figured that I misread the instruction then I went to the correct puzzle.
If doing the puzzles in a given order is intentional, it should blend in the story more, like each time I restore power, a a new door can be opened that allows me to do the next puzzle. Otherwise let the puzzles be solved in any order.
Other than that, it's a solid base for an immersive puzzle game with great visuals and atmosphere, I would wonder how it looks in VR!
