It is a neat idea, a solid effort for a game jam timeline, and the audio and visuals are fine. I think the gameplay can be polished a bit in terms of how concepts are introduced, to make it less punishing. Unsolicited advice to follow!
It is nice to use text ("did I see that move?") etc, but it so happens that the player can't actually do anything with jumping/swapping platforms on that first level, and may waste time trying to reach them (they seem _almost_ close enough) -- not realizing there's a screen to the right requiring the jumping.
I commend the evolving gameplay, but it comes a little too quickly, since the third screen also introduces the idea of three cycles to the platforms, and also added difficulty, since there are also enemies, and a little stairstep in the way preventing you from jumping immediately when entering. This 3-cycle mechanic could wait for yet a later screen, perhaps, so the player is used to jumping a little more.
Finally, before I gave up was the level introducing the cycling platforms ("did I see those rotate?") because, again, you can't do anything with them until you go left back to the other screens. The help text should probably appear in the same screen where you can use it :)
