When I have a better computer (which is what I have planned), I could leave the computer processing the animation while I use the other one to write the story. With that, I could animate the entire game just the way I want... But I think there's still a long way to go for that.
Still, the idea is for my games to be 100% animated and maintain the best possible quality in all aspects.
Regarding the routes, they are all independent and different from each other. No path will lead you to the same response or the same place (just like real life). My idea is for all the characters to connect at some point... But I think it will take me a long time to achieve something like what I have planned. For now, the routes allow you to be alone with that particular character, unfortunately.
I'll take that advice. The truth is, I'm not entirely satisfied with how I wrote Dakaria's route. I might change some details in the future.
