I played through your game a bit, it looks nice and the story sounds interesting too.
But I came across two game-breaking bugs that kind of makes it impossible to continue playing. :(
The first is that if you leave Carina's house through the backdoor (where Logan is) you can't get back inside. So you get stuck there unless you had a save from before.
The second is a weird one. The brother gets stuck in front of the sign if you go inside Carina's house (not sure if it's just her house tho).
I had talked with him and the event went ok, he moved from where he was and the path was cleared. But then I remembered that Leopold could join the party so I went to get him from Carina's house. When I came back outside, the brother was back to where he was before, in front of the sign so blocking my way out of the village. :(
Unfortunately my save is from very earlier in the game (before I had fought the frog, the rats and the spider, I don't want to fight them all over again! XD) so I'll stop playing now.
I do hope you'll be able to fix the bugs though! I'll give it another go after that because I really liked what I've seen in the game so far, I'm curious to see what will happen to the heroine! ^^
