My First Paid Game Dev: Code Walkthrough of Frogs And Flies on the Commodore 64

Today we'll take an in-depth look at the first commercial(ish) game I made, Frogs and Flies for the Commodore 64, published by Loadstar in 1997. I play the game, explain some of the history/story behind it, and then do a full walkthrough of my 24-year-old code!
