Ah, yeah. That's the only problem with Wario World too.
A bunch of Tumblrians/Deviantartists made three sequels, apparently. The new one (Incomplete, but what she published already is supposedly the beginning and it's already 1/3 of the length of the first game.) looks like she's taking it too seriously and not emphasizing the absurd surrealism, but I haven't played it, I'm just literally judging a book by its cover atm. There's also Earth Birth, which is about the same length, and the guy who originally made it declared it canon. However, for reasons I don't know, it's now apparently the third game in the series canon-wise, and the second one is 'Space Funeral 2'? I don't know, there's a Space Funeral wiki on Tumblr, I'm sure most of the games are great. Otherwise, there's always OFF and Yume Nikki.
