Hey, a fellow Japanese person (judging by your sign-off name)!
Thank you so much, this is my favourite Rakugo story so I'm very happy that you like my take on it. Also thank you for your comment about art.
What you pointed out is totally valid and it is exactly where I fell short... I made everything solo so I had to cut a few features. I had the ideas like chapter select options and flexible save system but I ran out of time. If I were to come back to this and work on it more, I'd make sure to include the said features!
