I'm sorry, I lost all motivation and probably won't continue my playthrough. Just when I finally had a complete (4 members) party... Since I'm a big fan of fighting with parties that are composed of at least 3 (better 4) members, my disappointment was immense when I discovered that I have to complete the next three main quests with only 2 party members (protagonist and one different sidekick each time). Apart from my design nitpicks, the game is competently made, so I hope you will reach and convince many members of your target audience.
With regards to bugs, you should make sure that non-healing skills can't be used from the menu outside of battle (Warold's "Taunt", Tommuz's "Vitalizing Shock", Yrana's "Sleepy Spell", though the first two might be intentional).
Concerning other feedback: It's nearly impossible and requires great patience/luck to trigger battles with bats. I'm sure that could be handled differently (better).
Thanks for making this game, even though - at last - it doesn't seem to be a game that I can wholeheartedly enjoy.
