Hey, I am glad that you enjoy the game! As for success?... unfortunately we're far from that. :D
As for the 20th power-up, that's the Time power-up, that is in Hard and Rogue mode only, as there it makes more sense with all the levels being Timer based. And yes, it may had been a silly idea to not pool together the knowledge of all profiles... but it's a lesson learned for the sequels. ;)
