Play as a blue creature (and his friends?) and traverse through a series of levels. They are currently 6 different songs, including the title screen music. If you wish to keep the title screen music, use "normal music." Otherwise, click "normal music" to switch to and use "random music." [This is the demo version, with only blu as a playable character. There is another version with a bit more content that I am working on.]
I used some scripts from JamesOuO's tutorial, no longer available for some reason. I also used some of Kevin MacLeod's music. As said in game, there are many glitches that I don't know how to fix. If you ever get stuck, simply press "space" to be placed back at the spawn.
