A fun format for a platformer game, with nice visuals and audio/music. I appreciate the ui work for the menus and pause screen, it's all rather polished looking for a jam game. I found the level design to be very good, with many clever uses of the mechanics and structure. It could probably benefit from an option to reset the level state after dying though, there were a few cases were different entity cycles got into a bad sync that made it hard to progress (plus it's a bit too easy to accidentally softlock with some of the moving blocks). I think it probably would also control a bit nicer with slightly more air control, which would make it easier to execute some of the trickier jumps.
Overall though, a fun and visually appealing little game
