Lovely choice of music! As others have commented, having the next move be telegraphed would be most welcome, as would a gradual ramp of speed. It would feel much more satisfying to be able to let your square rest for a few beats and drink up points once in awhile rather than having to constantly be flitting about, at least at the start. Sequential wave-like keypresses to move around is an interesting idea but I found it a little tough to play, I would really like it if the key-wave was relative to your current position rather than constantly having to start from 'A' and go left to right. Nice job, though! :)
EDIT: Just read your pinky trick on the game page. That helps a lot!
