The health pot issue was hotfixed yesterday, perhaps you downloaded the game earlier?
I'll change the trigger for the quest sparkles (currently: have Znahara quest & crossed the bridge at least once) so they appear later, about the old guy: I could make him stand still so there is no "maybe he will move away after awhile" thinking going on, which is what I imagine frustrated you.
I'm aware that puzzles are not everybody's cup of tea, same for the turn-based combat. I thought about adding a difficulty slider and an item or talent that gives extra hints for puzzles, or maybe add that feature to one of the difficulties.
Anyway thanks for the feedback!
