Bit late to do a 180 and start making self-indulgent games, there are stakes for him now. Zell's developed a fanbase over nearly 10 years of making nsfw games, and they know him as the monsters girls guy not the horror guy. Being self-indulgent and neglecting the fans is going to result in a loss of interest, and more importantly a loss of profit when this game hits DLsite. Not good when it takes him several years to produce each game, FOBs isn't even finished yet.
I don't know why nsfw game devs can't just be happy with making money and making thousands of people happy but they keep taking these bizarre risks. This shit has already happened with Full Flap, who heel-turned from their fans' interests by nosediving into 3D games for absolutely no reason. Despite having always knocked it out of the park with their 2D titles such as Demon's Sperm, they spent 5-ish years learning 3D animations and modelling just to make a god-awful Mario-like, which everybody hated.
