I have a suggestion for a futa mode (unless you have something planned), so it'll only be available where the dih would be able to be seen (or add an x-ray for scenes it can't be seen like frisk in the strapon scene), but what I can think of, let's say it's missionary then I think you should be able to press front button twice to get it and then it'll automatically go to buttfucking since there's kinda a dih there y'know? Or for sbj (side blowjob) there'll just be a futa mode button that you can toggle on and off. And maybe there could be a setting that gives them futa in battle. Also pale would have a monster dick~ anyways I'm writing too much so I'm gonna stop here
Edit: also would it be possible to make the person (chara or nebby if u add it for both) To cum with you if you have futa mode on :D
Edit 2: I have another suggestion, I liked pre-redesign chara (I also like this one too dont worry) and i'm sure other people also liked it so i feel like there should be a setting to make all the skinless chara things (battle sprite, scenes that were before the pre-redesign) back to the pre-redesigned version and maybe even add pre-redesigned versions for the scenes that didn't have a pre-redesigned version~
