Interesting concept, though I will be honest and admit that I had almost no idea what was going on at any point lol. A lot of story but I didn't feel like I had enough context to really put everything together, kind of seems like we start right in the middle of something that had a lot of prior explanation.
Controls were a bit touchy, made platforming at certain points a bit difficult. It all worked, just needs some tuning. Maybe play with the character rigidbody's mass and gravity, plus the strength of the jump if you're using velocity.
Can tell a lot of work and effort went into building the levels though, there's definitely a ton going on and lots of objects placed to build up the areas.
