THIS MAN ISN'T CRAZY HE'S A GENIUS
Where did you get up to in amplitude? I pride myself in having gotten to the "secret" song, which is probably my favorite in the game (and that awesome halo! awesome!) Other than that, I like super-sprode, and also I do epic singalongs to that Pink song.
I never played frequency though. I did enter a cheatcode which emulated the Frequency style, and I've gotta say I'm not really a fan.
If you wanted to get married, thought, that would be fine by me.
