This is yet another time/energy-limiting mobile-style money-grab game, with a model based on annoying the player into paying to be allowed to actually play more than a minute every few hours. I would discourage players from investing nay time into it, and Kongregate from encouraging such developers.
Hey there! Questing represents your general adventuring, and the damage is representative of general negative impacts, not just "getting beat up" :-). Many instances will, through the story, involve actual combat, but others can be stress, lack of sleep and such, too. This damage can be mitigated by Defence (more noticeable at higher Difficulties).
The bar you're describing sounds like your Energy bar, not health.
Finally, Quest Bosses can damage your health, and require Energy to defeat, not Vitality.
We are glad you seem to be enjoying your adventure thus far!

The text of a game should be the easiest thing to get right (compared to the code). If they're not willing to do that, I don't have very high regard for the developer.
