I am actually very excited to hear that you are planning to continue after Summer Scent is finished. I really enjoy watching artists as they move from project to project and how their work evolves.
I'm not looking for any answers to any questions here, but are you planning to do another visual novel with multiple routes? It seems like having a lot of routes multiplies the amount of work involved. I know a lot of players want this freedom of choice so I can understand why a game dev creates their games in such a way, but, as a player, I rarely have replayed a game to see how another route turns out. I guess I like that sense of closure that I get when I when I turn the last page of a good book.
Anyway, I'll be looking forward to your work next work when the time comes!
