It was a bit of burnout, but mainly I wasn't satisfied at all with the game. I felt it was incredibly derivative of Didnapper without any of the cool new mechanics that defined it. I wanted to do a whole reboot, and cutout a ton of the monsterlords to fleshout the story ones.
But the project in the reboot lost steam and I prefer to cancel instead of dealing with sunk-cost fallacy. I do still wish to do something with monstergirls, if you have checked some of chinese year it had references to a Queendom full of monstergirls, but I gotta see how that project pans out.
