Thanks for the recommendation, but I have already been using Unity for more than three years and made few games with it, but sadly, we haven't published any of them yet. But I'll check RPG maker too.
Yeah, we beat it, but we cannot find the secret side quest (quest about the yusha, I guess). Can you give us a hint?
And were there multiple endings? I thought there was only one. We'll try to find them. BTW, it's a cool game. Do you know some other games like yours?
