Nice concept and presentation. Unfortunately I couldn't switch blocks as the scroll somehow doesn't seem to be working with the trackpad. This meant I could pass only the first level. Music is good. Well done overall!
You can use 1, 2, 3, to switch blocks. Sorry for not mentioning, massive oversight on my part. Thanks for the feedback!
Ok, that works! Still couldn't pass the second level though :) Will try again sometime.
