Wee feedback about quests -
New quests - When the rock gives you a new quest, I think in a previous version of the game, there was a notification that the quest had been added to your Quests list? But it seems like in this version, when the rock asks you to do something, there isn't any notification. I remember from last time that I can click on the rock and see my quests list, but it might not be obvious to new playas.
Rewards - After completing a quest the rock says something like, "You did it, so you get your reward!" but then there doesn't seem to be any notification about the reward, and looking in the Quests list, the rewards don't show anymore for completed quests.
