Well that took me back in my Myst days ! Excellently made: strange machinery with good atmospheric sound, a sweet puzzle to solve with a "aaaaah of course" moment, and a personal touch that makes it unique. Only wish there was more, I'm so addicted to this kind of games ^^ Maybe I would have add a bit more ambiance musics, but that's also part of the style. Controls are smooth, no laggy animations, the aesthetics are great.
Anyway, I'm impressed and happy to see this kind of games can be made with Godot up to a high quality standard, I wonder if the resolution can be push a little though. Great work !
