New weight stages will have to wait until I redo how the player sprite is drawn as adding new variations (like weight stages) ends up requiring adding dozens (maybe 100+) of new sprites to the project.
Additional vore types are still something I'm considering but I wouldn't get my hopes up too high that they'll be anything very impressive. If I do add them it'll probably just be some kind of flavour change. Maybe things like new internals animations, different quotes and altered disposal sprites.
I understand, It makes sense for the weight stages to take a long time. I do like the idea of new internal animations for like unbirth/the womb (swelling), anal vore/the intestines (reversed animation + swelling), breast vore would be harder because you would have to add breast size increase = a lot of animations...
and if you ever planed on adding a new body swap to allow futa, it would allow cock vore to be added, which would mean a lot more animations. And now I am wondering how all these vore types would interact with each other animation wise and button wise they would all have to have their own button and probable their own fullness bar... yeah that is a lot of work...
