Finished it and enjoyed it as much as any rpg maker game I have played including commercial rpg maker releases.
Some things you may consider fixing.
If I return to the room after rescuing Jana the sequence begins again, pretty sure that happens somewhere else but don't remember where.
Party characters are in their original place after joining, was this originally intended so they could later be dropped as with rick?.
I never did find the kidnapped mayor after letting Barbara escape, seems he may be on Vahiti island.
There is sometimes a boat for travelling to Vahiti on the beach outside heraka when you travel from aldi to heraka, game locks up if you select yes to go there. How to find/get there?., nah I may play again.
Money never goes down when you get the guy to convert the potions.
Not sure it was intended there are at least three crosses but you only need one and use it in all three churches.
I can see another part of frost tunnel, is it accessible?.
Do you intend making another game?, I would be happy to beta test.
