A simple Minecraft clone written in C using modern OpenGL

Looking in the github issues tab. This is so hilarious! There are a lot of people posting their Minecraft bugs thinking this is the official Minecraft repository haha

The code is full of one character variable names. Why do people do this? Even if I was programming on my own one-man project, I wouldn't do this. Why force yourself to keep all that context in your head? Do you still know what everything means after a few months away?
