I had an error, something with java runtime, but I just opened it in processing and ran it from there :).
First, I just want to say that it is really really cool! I really want to see what you do with this concept, but I got stuck at level 3.
There were four main reasons, I think:
The controls: why not add wasd controls? Or even just add the ability to jump by pressing the up arrow? It takes seconds and opens up your game to many more people.
The friction: please, please, add more friction. It feels like I am moving on ice. It makes it frustraiting to do the most basic jumps onto moving platforms.
The explanation on ghost blocks: it was partially blocked by the plank on the top, and I couldn't understand how the music affects them. Which brings me to the fourth thing you should change, I think - every time I wanted to experiment with them and died I had to go through the tape part again, which was even more frustraiting because of the low friction, and I eventually gave up. I suggest you put a platform underneath it to allow the player to experiment with it safely, and get the hang of it.
So please think about those things, and if you do chnage it let me know, I would be happy to try it again. But I couldn't get through level 3.
