How much can you change in the regular world as of the current release?
The current Public Release (0.4.6) only has the first "IRL" transformation (the one with the glasses being removed, etc).
The current Patreon-only Release (0.5.2) has one other transformation afterwards.
The "IRL" transformations are meant to feel gradual and slow, while the content in the protagonist's other body can be a leap further forward in physical femininity.
Thanks for playing! :)
