I just come here every once and a while to post this. They will not be updating this game. However, they are currently working on making a new game that is basically a sequel. Here is a link to their devlog: https://ci-en.dlsite.com/creator/16553. Current Expected Release date is early 2025.
For Non Japanese speakers speakers, since it is entirely in Japanese, I would recommend using google chrome's feature that can automatically translate all the text on a webpage to a chosen language (I use it to read the devlogs, and it does a great job).
P.S. to Drevas specifically, the creator does intend to add a setting to allow you to be fucked by the people who catch you in the new game.
