A fun little game I heard of that might be fun if I recreated it. This version of Duet is much different than the original. This one you have points, is endless, and has an inanimate background. If you want to know more about the actual duet, go here: http://www.duetgame.com/ All hail Kumobius, the creator of the actual game! Oh yeah, use arrow keys to move the two orbs around, and don't let them hit the white walls.
Inspired by Kumobius, and music is the level Polargeist from Geometry Dash, since I could not find any normal level music from Duet. Oh boy, scratch really destroyed the quality of my music :P
