Hello. Thanks for the reply.I think Complex Breeding has huge (4) as the biggest possible womb size. But since the main post about CB was deleted by the author, I can't be sure.
The developers' work on this game is done. Do not expect any new updates. They are working on a new game, called ProjectR, now.
MBM is not very mod-friendly, and apparently ProjectR is more mod-friendly, so you can expect modders to migrate there when it's closer to completion.
It seems that there is only one person on these forums who really understands how their animation works. He made Tits mod for MBM, and wrote a lot in ProjectR's comments.
Everybody else, even with changes as massive as Complex Breeding, uses the assets the game already has.
What a shame, this game could be much grander honestly, if it had more content.
About ProjectR, I've already played the version here, but honestly I didn't like it very much. They follow the same style as: MudBlood and Goblin Lord Wants Me to Become a Virgin Wizard by Managing the Brothel!
Basically you have a window with the goblins and slaves. I don't like this style very much.
I think that instead of the developer making another game with the same idea, he should make something similar to the first but with a different theme. Like a farm manager you know, something like this: see image
