Intriuging! The theme usage tie in requires some suspension of belief here but I don't mind it, it looks like it inspired an interesting mechanic. I think some of your levels are not as "elegant" as they could be but I think that's a given for a game jam game. Some platform heights / collisions maybe could be tweaked a bit, but overall it was enjoyable to go through the levels.
It feels like the default canvas size on your itch io page is relatively small given the scale of the levels (?). I think my main critique would be that since the strength of the gameplay is more on the puzzle side rather than on the tight platforming execution side, overall the experience might be better if the gameplay is slowed down a bit (slower gravity) to allow for more lenient timing. I didn't find it too difficult, but again I personally just feel like difficulty in execution gets in the way of letting your interesting mechanic shine.
