Perfect music for the game. Mashing the arrow keys to have a rainbow behind you is fun. Changing colors to ride certain lines is a nice little feature. I wish the vehicle could go a bit faster since the music is fast paced and I imagine the vehicle should be fast paced as well. I changed my color halfway through a line and got stuck in the line causing me to restart the level which sucks. Until "The Cave" it felt like a giant tutorial to me. After beating half the game I was tired of the music since it is just one song looping over and over. I also was done after completing half of it because I feel like I got cheated out of medals. There should be some medals in this game.
