I enjoyed this (though I suck at platformers so it was pretty hard). I was skeptical about the segmented-levels instead of just being endless, but it turned it more into a puzzle game about planning your moves instead of just a reaction-time based game -- though it still requires good execution. It'd be cool to expand on that element if y'all wanted to make a post-gamejam version. My only suggestion would be to maybe start the first platform of the new level in the same spot as the last one of the previous level -- to make the level transitions less jarring. That would give the best of both the endless and segmented-level worlds, IMO.
Also, the art is great!
