Thank you so much for the detailed comment and all the love haha! :)
We really loved developing Chiharu's character as well, she's quite iconic haha.
A lot of people seem to want to see more of Shion/Sora and this makes the team really happy! Shion and Sora are actually almost my (Kazuya's writer's) favorites. While there's no more content planned yet, there's a lot of interest in them so we'll see! The team has been joking about Shion working as a coffee shop barista in the future, so we'll see - you never know haha.
Regarding the art: The game was created for a one-month jam originally and because we'd originally intended for the game to be much smaller writing-wise, we only had a few CGs and sprites planned. We hope you still enjoyed the pretty art which is there though!
As for the rest, we'll have to wait and see what the future holds! We've all got separate plans for now, though we're still keeping in contact as good friends / helping each other out on future projects. We might get back to this or develop something else together with this same team in the future, but right now we can't guarantee anything. <3
