Ey! Reminds me of my middle-school years! I still can't belive I made an entire game without a single class... Just storing info in arrays and writing in comments what location represents what data. But I was a literal child, too young to read guides or sit through "long" tutorials.

I don't want to sound too mean, but whenever I see anything similar at work, I wish that person get a job they're actually good at. It's fine and all that the company started hiring actual programmers to fix things, but the fact that the old crew still fucks shit up with senior privileges is a major grievance.
