Hi, thank you for your support! I understand your request, however all the animations in the game are fully hand-drawn, frame by frame.
Adding a new girl with a different body type would require reworking all the animations to match that change, which would be a fairly large modification.
To partially address this request, we are adding an inflation animation instead.
This new animation is contained within a single room, which makes it much easier to manage.
In any case, I invite you to share your suggestion on our Discord server in the suggestions section.
Have fun!
