A 'kiss unmasked' mini objective would be fun. Like once you hit all multiballs in one game you can go through and do them again and unmask (yeah, it would be new dots) the band members...

Or maybe something more basic like once you've collected all members you can collect them again 'unmasked'...Of course it would be AWESOME to have a phantom of the amusement park mode....!!!

EDIT: I know this was for bugs...Sorry, theres just so much they could do with this theme...Anyway, ball save during multi when genes head is active...Thats my bug fix wish, not sure if someone said it.
