Steele,Ronan and Davis awesome work! I liked the music selection and the art. I believe your game would benefit to have a tutorial/controls option.
Critique: I was lost on how to play as I wasn't sure what notes were for up, down, left or right. This may be a failure on my part as I do not study music so it was hard to understand and play. I also had trouble figuring out if I was supposed to use WASD keys or the arrow keys at first. I did fail epically to play the game and the ending didn't loop back to the title screen so I got to see my poor ballerina sit there in defeat until I left webpage completely :,(
Overall making a game in 7 days is tough and what you put out is awesome so far!!!
I hope your team continues to make games!
