Very nice look and storyline, but...
The skill costs to opponent strength balance is way off, it the gold cost vs exp cost also. The game is badly imbalanced.
It's repetitive. Also, you need more "overview" ability, i.e. checking potion quantities out of battle, map of forest explored so far, the ability to re-equip past "other" gear.
Give a feeling that the game is linear, grind-based and choice-less: move, mow down opponent, raise skills, repeat.
Fixable, but needs a better design flow of play design. Too bad, I usually love your games.
