Well, man anyway. (Although I'm fat enough to be considered two men.) I did it. I designed the final level of Ugly Uppity Umpire for Game Boy. Now it has 50 levels. I started last October, so it took about a year of off and on work to design them. Like about one level per week. Although I made the last two levels today. Now what I need to do is make some sort of ending and I'd like to put in a Super Game Boy border. I have room enough to do both since I have two unused banks left.
It's been a lot of work, but I accomplished my dream: Programming a game on a console I grew up playing. After a crappy NES game, I think I have the hang of making GB games with C. Too bad Frank the Fruit Fly never got published. Hopefully my choice of not using a battery for Ugly Uppity Umpire will pay off and I can get it published somewhere.
