Personally, I find "I Wanna be the Guy" to offer a false sense of being challenging by dumping a bunch of arbitrary bullshit atop their players. It becomes more of a game of trial of error and memorization than anything else. It bores the snot out of me that way, and I regard people who become really good at it as being complete tools for its authors: they think they're being challenged, but they're actually just being strung along by their egos to dance to the authors' tune. Still, it does have some neat sight gags - it's not without pop-culture artistic merit.
