I think the idea is very fun, and some of the solutions I figured out for puzzles felt very rewarding. I do think however that the platforming can be a bit too precise in how you have to execute it, which often takes away from the feeling of discovery with solving the puzzle. I found several times where I figured out the solution, and simply could not get the platforming to work like I intended it to, which took away from the satisfaction of solving the puzzle in the first place.
I do think that the core is there, the idea of using past selves with rotating gravity to help future loops is a really neat puzzle to work around, I think the game just needs to focus more on either the platforming or the puzzle element, right now it is a weird mix that fits between the two in a way that takes away from some of the satisfaction of both.
