great take on the title! the time loop is such a great way to inject some emotion into the space. i'm impressed you were able to fit three tonally different descriptions into each area while keeping the flow of things comprehensible. it tickles my brain in a good way that the rowboat the players come in on only exists at night in that location.
high: the fog!! wow. the image of walking through this sea of mist only for the time and atmosphere to be radically changed when you emerge is killer.
low: the lack of clear solution is very cool, but it makes the (understandable) lack of clear reward a little limp and uninspiring. something bespoke from a few possible parties would add some extra flavor to their character and elevate this, imo. i'm iffy on some of the blank spaces in the loop itself, like the details of the sabotage - i don't mind figuring that out on my own, but i think specificity would be more fun!
in-between: i straight up thought the astrarium image was a kitschy sci-fi pull until i googled it and saw it was just like. a real thing. wild.
