Think about it: loads of uninhabited buildings, plenty of ruins, only two inhabitants, it would probably make sense. Maybe Ix used to be a vibrant metropolis until some great disaster happened, (I'm betting that the sky fell, probably due to a Rook attack, hence the cracked sky,) wiping out everyone but Uncle Friendly and Helga. This backstory for Ix would not only add some depth & texture to the world and it's history, but it would also provide a way for user-generated content to the game.
What if Uncle Friendly & Helga decided to get together and repopulate Ix? Of course, they'd need somebody to help build some new streets (and possibly some new colonies on the other Miscellaneous Islands) for all the Uncle Friendly/Helga slugbaby things. That's where you come in. Glitches with the right skills could use a Street Editor to design their own streets, then submit them to Uncle Friendly. Other glitches could vote on these proposed streets, and the one that gets the most votes is incorporated into Ix's expansion/colonization. Uncle Friendly & Helga's babies could function as the the street sprites for these new streets, and street designers could dabble in more art styles as the people of Ix spread to the other Miscellaneous Islands.
So whaddya think? Shall the great land of Ix rise again?
