Thanks for playing, and I'm glad you enjoyed it. The game is still evolving, so there's a lot more to come, including lactation. I'm currently working on how to implement it. It's actually quite challenging because of the huge range of possible boobz sizes, especially since they're not handled through a rig (the same issue applies to nipple piercings, by the way).
If I knew how to implement passwords through itch, I would definitely do it. It's a good idea. I think it would be much more convenient for many people, especially considering that not everyone wants to sign up for patreon. But for now, I simply post the passwords in my patreon posts, and I don't have an automated system yet.

There was one game I saw that implemented a cheat password through just having a TXT file locked behind a paywall, but I don't remember what it is.
Also, I figured there was something like a rig considering the nipple growth potion. Does the part of the nipple that grows have something to anchor a particle emitter onto, or is it not that simple?
