Oh, wow, is this a randomly-generated world where you need to get as far as you can and get a high-score? I like that idea for the theme!
An easy and clever way to include the theme, without actually making it!
I've already posted two updates on my game. It's a 2d puzzle game where you have to arrange the numbers to make the equations actually true. And I've kinda just taken the theme, removed a letter, and made a game around that.
I've used GameMaker as my engine, aseprite as my sprite editing program, incompetch.com as my music source (can't for the life of me make music without a mute button), and a couple of friends as beta testers. I'll probably also use bfxr for a couple of sound effects.
