I read there's supposed to be some sort of horn you can get to triple your lollipop production even past the 100/s limit, which seems massively useful. 100/sec is far too slow for getting some of the better upgrades.
I've been having mad trouble with the boss in the Castle's Keep. I use an invulnerability potion, but it wears off before I can do enough damage, and he kills me before my cooldown is finished so I can't use another. I think I might need to grind candies for HP.
On that note, what's everyone's favorite quests for candy grinding? I had good luck with Underwater Cave at first, but now it's too slow to really be worth the effort. Castle's Entrance seems like it would be good, except I can't find a way to reliably avoid those cannonballs (or arrows, or whatever they are) that send you back to the start; the best I've gotten has been berserk potions, but those are not available in the quantities I'd need for grinding.
@xLostWingx: This game involves a lot of idling; it takes a lot more time than you have to personally invest, and you can easily do other stuff while you play. It's quite addictive, but not life-consuming by a long shot. Also, I suspect it can be beaten in a few days, sooner if you use good strategy and don't buy the life sword like an idiot like I did.
