Hi there, this is a random suggestion- what about the use of a world and games... I enjoy the tasks but thought maybe with the bad guy section a daily battle of sorts- like a get you on edge adrenalin pumping game... maybe a hammer and you get points for hitting the bad guys and the more you play the more harder it gets. Then the different quests are in a world where you follow paths to the quest set. Like the chill pill quest could be next to a beach and the different areas are locked until you download it. Using that when you enter the location you enter another world which you can see your task awards plus how you achieved them in a more organized way. Also rewards such as collecting pieces of a puzzle which link to a short movie about it (don't know about copyright infringements) so for example the being awesome challenge you collect pieces to a Lego man type puzzle then the "everything is awesome" song plays... or even that stupid cat playing piano just to give people a little boost. I know i am rambling for africa and it is probably a bit farfetched... ooh oooh and for the stop smoking one- a game that you have to put out cigarettes which are going to burn a house down... i think people won't enjoy it though because it may be a bit too childish. . . anyways thanks for taking the daunting task of reading my suggestion!
