Loved the game! Buggy in a few spots (after first section when hitting B and last section after Mango part). Loss of progress seems to linear and predictable. Almost loses it's Foddian nature in my opinion, but still a great concept and wonderful execution. I'd love to see more levels/songs.
P.S. The slowing down and speeding up of the bar and words seemed way to unpredictable. Having it more consistent would be my only suggestion for improvements.
