I’ll be honest, I just copied Avery Moore’s code from here, the first time I tried writing a CS game. I spent more time play-testing it to ensure it ran smoothly, than directly auditing the code. I know, I know. Skipping code review? Bad programmer, no cookie for you!
I tried using variable names that reference the strict grammatical roles of each pronoun, but that was more in hopes that I could finally remember all their names. It failed.
