Sorry for the late reply, I appreciate the feedback! Funny enough, I was also replaying over the last couple weeks, and I have my own long list of bugs and ideas for improvement.
At this point, it's unlikely that I will continue the project as is, but I have been planning a reboot that would be web-based for maximum compatibility. Being web based would also make deploying changes much easier, as well as things like bug reporting.
I'm also very interested in making "custom girls" a thing, allowing players to upload/share their own JSON (or similar structured format) to add girls that they want that are missing (on top of the regular updates of girls I would be adding myself). If that goes well, I'll explore more wider reaching open source ideas.
TL;DR: no concrete plans currently, but I plan to make the project bigger and better in the future (pending some current IRL blockers).
