Welcome to "Refactoring A Game A Day" (RAGAD)! The idea is that I will try my best to explain my old games that were coded in JavaScript using p5 every night! My source code is all made available, and I recommend you to build off of what I've coded!

Please do suggest future games I should make!

All source code is available at: https://github.com/Kaelinator/AGAD
