Masturbation option: Approved.
Outhouse for making fertilizer: Interesting concept, might tinker with that.
Farm/Hut customization: Big yes, but not now.
Herm MC option: Maybe someday, adding third gender option will require making even more scenes and adapting some things, might take a while.
Replaying sex scenes: A gallery is necessary indeed, will add.
A story mode: Oof that might be kinda hard to make, so only arcade for now.
Upgrades for your character: Didn't really think about that... There will be metaprogression and items, maybe house upgrades, but i didn't think of upgrading the character itself yet. Noted.
Character customization: DONE!
Option to change the vendor: Yep, did think it'd be a necessity.
Weight gain/ body expansion option: Oh god i didn't think people wanted it so much, oh well i guess we're rolling with that then, but also later
Optimization: It's kinda hard to figure it out, i will try my best
More character interaction: I doubt there will be a fully fleshed out dialogue system, but there will be more interactions.
An option to fuck the plants: yes.
A kink disable option: no. :^)
(well maybe if i will add something like weight gain then yes)
