Literally the only game that's ever made me hard for Goblins (Goblin daughter and Seqouia, not Shakhala though), by far my all time favourite impregnation game, the animations need some work (too short with no option to loop) but otherwise absolutely fantastic.
I am curious however if Tinkerer has any plans for the NPC kids you have to grow up (particularly the daughters...) or if they're more-or-less mainly filler for the preg fetish. Also very excited for MC's mother and sister to show up and for more content with the succubus daughter
