Beaten it maybe 4 times? Or maybe it was re-fighting the hard bosses that's got me. I always mix up the levels but I want to say 20 or 50 something.
Yeah, that's why I played through it more than twice. I first started on Normal, but each and every time, I mixed up the order of the worlds and later, what I picked at the beginning, though I started answering the questions differently after the second time. My last play through was on Expert mode. I might play through it one more time, but yeah.
