Super fun and super creative! The biggest improvements are in the juice, I would like to see a lot more game feel and reactivity to my actions.
I also found it extremely hard at times to tell which platform was next due to all the greys looking similar. Some color or some other way to give a sense of progress would be good for game feel and communicating information to the player. I also found myself playing by keeping an internal rhythm. This made the timer at the top useless. It would be really good if there was something closer to the player that gave a sense of when the next platform was coming. I really liked the sound design of the platforms, is was so satisfying to get in a good rhythm and clear a level.
All these critiques are minor, and you did great work especially on the level design. The concept was iterated on in some neat ways! I would totally come play again with some more polish and some more levels with new mechanics.
