Flash Dance Flash Dance Revoloution Remix!

This is FDFDRR, like the old one, but this one has music.
The levels aren’t on difficulty but on how long you can go for. The last one being for the whole song.
Edits in new version——
More colours in rainbow gradient
Song added
Levels depend on amount of arrows
Highscores fixed (hopefully)
Arrows given bevel filter

Now, please tell me what MORE i can improve in the comment section.
