Do the candy hearts this year have a purpose (like last year you could make the antidote for your virus from them I think) or are we just collecting them thus far with no real reason? :P

Just wanted to know if I was missing something!

Currently they don't seem to do anything, apart from collecting for achievements. :)

Well when you collect them you get a message saying to hold onto them. I don't remember seeing that message when I collected them last year.
