In what way does your game fit the theme?
The game invites chaos. Two players go through side-scrolling levels. Each player controls the tempo of the right or left hand of a piano piece with his/her movements. Once out of sync, a normally nicely structured and rhythmic music becomes a chaotic jumble of notes...

Did you write all the code yourself and made all the assets from scratch?
I wrote nearly all of the code myself. The camera controller is from the very first Unity-tutorial (roll-a-ball or something like it).
The original tileset for the background is from a Brackeys tutorial on tilesets, and I modified it. All the other artwork was done by me.
The music pieces were composed by Bach, Mozart, Chopin and Beethoven, and were preformed by musescore. The notes are all exactly the original pieces.
