This is a super cute game! I'm actually impressed that not more people have made rythm games, as it seems to lend itself very well to the time theme. I really liked the concept of the game, unfortunately (and ironically enough) something went wrong with the timing of the music in relation to the movement when I was playing, so it was more or less impossible for me to match up the movement beat exactly, as it was shifted a bit. It took me a while to reach a bit into the second level before getting thrown back instantly by a drone. I'll return to this game later, in another browser, where I hopefully will have some more luck.
Nevertheless, I think you have made an awesome game! Well done creating this :-D
