While digging through the DCBlap assets over the weekend, I came across this old easter egg: there are 13 additional title screens that the game could randomly display, with a bunch of inside jokes, Futurama alien text, and random quotes on them.

I can't remember how to trigger this anymore, I think it was by pressing a certain button on the controller at the Options screen, but it seems this was removed in the latest version of the source code I have 🙁
