I really liked it man, good job here, I'd say yes one problem is the acceleration but what really bugged me were the parts where the music isn't changing but you don't keep up with the speed you show just before and so it's not always going up and up, that can be a problem.
Another one is some scenes don't go with another one because of the colors, you go from red to blue without any transitions and it's "shocking" the eye sometimes.
But anyways, nice job! See you to the next!
