Hello! I played your game! Although I've only played for the first hour. I got up to the part after exploring the forest and you enter a town with a large library. I can definitely see this game with replayability options since you can choose who you play as at the beginning.
One bug I might have encountered was that you can't really run from battles, since the roaming monsters will place you into battle right away after. If there was a way to make invincibility frames for your party or have the monster stay in place for a while as the players run away from it, I think that could fix it.
There's one more bug I encountered, which I think you just forgot to set a movement route for. When you pick the third character, the cat girl, and say "no" she ends up staying in that spot instead of getting back in line. This might make the game freeze if a player were to reselect her and say "no" multiple times.
With what I've played so far, I do like what you've done. The narrative is natural enough that I can get an understanding of who each character is.
I do like what you have going so far and I'd like to see where you'll be going with it! I think the last suggestion I can make is to balance the gear/spells/battles a little better to make things more even for the players. (also do the monsters respawn? It felt like they did but I couldn't tell, they just seemed to keep appearing out of nowhere!)
