anyway jack/jill are not really interesting, the light changes they got (tail) isnt much to talk about, heck I interacted more with the nameless rusher (that keeps getting more and more tainted) than with them (and I really want art for that rusher, no idea why they dont have any)
I think it doesn't help that ultimately you literally meet them like 6 times.
Let me repeat, your
main rival shows up 6 times in the entire game, and it's pretty much only once in those encounters (intro, mhen'ga, tarkus, myrellion, dhaal, phaedra) not counting the repeatable scene where you give them oral in Uveto, they are more of a flat character than fucking Plank from Ed, Edd n Eddy, they are are really non-existent you could remove them from the plot and it would largely remain the same.
FUCK! you could even maybe make Dane be the one going after them, say he was hired by your uncle Maximilian (aka the cousin's father) to go and grab the probes and quits on Myrellion after Taivra incident.
He looks more "inbetween" then standard male.
Also to actually answer to original question, I was going to say Jill but seeing them side by side it looks to me that its just the same base and they "femmed" jack to make jill, so now it just feels like the jill design was an afterthought.
Though thinking of it now your rivals being twins with a theme naming, now that's an idea there.
I disagree and think that Jack is the afterthought and not Jill.
The only diference between the two (outside of breasts) is that Jack has noticeably less hair, he still looks generally more like a twink rather than a dude, additionally his thighs are still rather girly though Jill has more of them.
His chest feels like it was edited down to decrease it, it looks weird if you keep looking at it.
and apparently the incest route was shelved for them which is weird because it kinda felt that was the route. if I recall correctly if you loose the fight to queen taivra you can keep her as a slave in the game over screen so not sure why they're so scared of incest in the game
Shit really? that's pretty dumb lol, i think it's because Patreon was bit more tight on incest as of recent no? but I think Cousin should still be more than fine, hell they still have their Oral scene in Uveto too!
And yeah Taivra ending makes them be your bedwarmer, Frostwyrm's ending also gives the minor implication of that too (and to show off how you are doing well with your 100 frostwyrm direct and adoptive children with your 3 dragon spouses who adore you)
