Hi. Nice game but I didn't finish it because of the difficulty curve: I beat mosquito, beat slime and then dancing fancy skeleton beat my ass :)
You mentioned that it could imbalanced and it is. Maybe add more easy enemies in order to find more potions, items for player to get used to the game overall.
The story sequence is good and I enjoyed the dialogues and cut scenes.
What's really cool is the way of choosing the class. And some of the classes are intriguing.
Anyway, that's great item here and I loved that you managed to create JRPG because I'm kinda fan of it.
