W RGB CMY K?

W RGB CMY K? is a reaction and memory game played in a single pixel. It's an experiment in introducing mechanics with as little explanation as possible.

There are 12 levels  in the game. The controls are W, RGB, and CMY. K?

The game was created for the GMTK Game Jam 2019 with the theme "Only One." The source code is available in this GitLab repository. Be warned, that code was written during a jam, and is very much a mess.
