I only had the chance to give your game a try today and unfortunately today was a bad day so I didn't have a lot of time to play it but I liked what I've seen so far from it. Story and visuals are there. But. You need to find a better way to connect the story with the gameplay.
While the story is really interesting (I love having to fight demons! for humanity!), I kind of got lost when the introduction ended. >_< And the old man that said would speak to us if we were to seek revenge kind of went missing? Where he go? lol
I find it funny that I kept finding the same books in all bookshelves.. even when in other inns in other cities.. You need to change that up a little, to make it interesting
I kept moving around the map trying to figure out where I had to go after that but the only clue I had was that I needed to buy some weapons and then later to find a mountain pass? All good.. except I got no clue where that mountain pass is and I'm dirt-poor.. haha (You could have given us at least a few potions! So I could sell them back for some money.... xD)
I ended up fighting some monsters in the world map (and getting enough money to buy the best weapon I could find) while exploring but I always felt like I was missing something.
I think your game would gain if you were to add a quest log to it maybe, just to remind the player of what they need to do and where they need to go. In the objectives you could even add some guidance about where is the locations we need to go to. (Some signs in the world map to guide us would be nice too >_< )
Another thing I noticed in the towns (I could enter) was that there were a lot of houses that had no door? And we still couldn't enter like 90% of them. I felt that was a bit disappointing. What's the point of so many buildings if we can't explore the inside of them? I was also sad we couldn't visit the Academy where we studied (and the other one too) and not even the Castle? :( The guy that welcomes the injured people says if we are wounded we could go to the Castle for healing! False advertising! :P
The battle system looked balanced, I thought the monsters' strength was just right, they were not too hard and also not too easy. The skill set I tried looked nice too! ^^
PS: In Minich'i when you try to enter the houses the faceset that shows up in the dialogue sayin you can't enter is from younger Komui (when we are already older and hotter lol). You gotta fix that
Overall: It looks like you have the game all set, you just need to find a way to connect all dots better. The story is there flowing nicely, the maps are all set, but you need to find ways to get the players interested in playing it and then keep them playing.. while working on that you can also improve your maps, make them a bit different from each other (because the inns are pretty much all structured the same xD)
Good luck and keep working in the game because it does look interesting! :)
PS: The crystal in the intro is really pretty.. ♥
