> do you plan to make a R18+ version of the game
No plans right now - asset generation for this was pretty intensive and R18+ would require redoing a ton of them. The latest update should have some more nudity and things you may find interesting though!
I have zero desire to make any money off of any of this stuff, though.
> do you plan to update the sprites to have them correspond with the transformation
I'd love to be able to do something like this but it's a ton of effort in an area I'm pretty unfamiliar with. Maybe I'll find an artist who is interested in partnering here, but I probably can't manage it myself
