The last time I play this game is on ver 9.5 , I play this game again yesterday but there’s no change for Dagio route except the main story and sprite , is there something that I do wrong or is there no update at all for Dagio ?

A few months ago, I created a post on Patreon to see what my patrons wanted me to focus on.
Currently the main story line and Janus is what they want me to focus on.  I create the same post once a year.  We'll see who the crowd wants me to work on next.
