That was very cool. I like the soundscape a lot, and the screenshake is a nice added bit of game feel.
I do feel like the section before you get the grappling hook is a bit slow, as much of it is waiting for platforms to move above or below you, it felt like the levels could have been squished a bit to keep the flow from halting as much. Also the player hitbox is a bit bigger than the player sprite, which led to a couple of frustrating deaths.
When you get the grappling hook you lose the issues with pacing, but i also felt like I never really got a feel for how it works. There were a number of situations that felt like I was supposed to have higher precision with my use of the grappling hook than what was reasonable to expect from the player at that point.
Overall, though, I like the variety of the level designs, I think the ways you use the concepts at play are very effective!
