I'm slowly getting there, I just need some time to finish the code and the artwork. I don't know how easy/hard it will be to properly add body modifications, such as body part sizes, but seeing the chastity cage in some of the scenes is something I'll add very soon! Body modifications would be hard to add into the sex scenes tho, so I don't know if that will be possible (I'll try if I see a way how).
The next update, which comes out today, features a dedicated scene to the cage where an enemy locks it on you and you'll have to either buy a key or find one to break free.
