Hey, Gabelgyum. I love all of your ideas! As you noted, I haven't added any new content since August of last year, but I'm happy to say it's because I'm currently hard at work on another game I hope to release in a few months.
As a result, I don't plan to revisit Campus for a little while yet. When I do, my plan is to make a few minor changes and then call it done: v1.0. However, I've grown a lot as a coder over the last year,and I believe the Campus concept is too fun to leave as is without letting players stack transformations to get the giant/tiny/thicc/grotesque characters that they deserve! So, my intent is to cap off the current version of Campus and then, shortly after, release a polished remake that trims away some of the fat in order to make more meaningful and impactful transformations, like those you've outlined, feasible.
This is all to say that, though I likely won't be able to do anything with your ideas right away, I think they're great and I look forward to when I can include them in my next project. If, in the meantime, you'd like to share more ideas or play some other hot gay text games, consider joining the Homotextual Gaming discord server!
