For the questions in the comments, this is 2013/08 version. As far as I'm aware, it is a trial since you are unable to freely access the CG gallery. You can see a few rough sketches in there which I assume will be finalized at some point.
I like this guy's art. But damn. I see plenty of human sex. Tentacle/monster births are nice, but I prefer human ones, it'd be cool if those were also an option. In one of the manga's he made there's also mention of a human impregnation. Is this game still in development? Any status updates? Does this guy run a website too? This seem to be on RPG maker format too. That'd be cool, since I could actually play it after I buy it haha.
A moment of silence for an ambitious game which will never be completed.... RIP EDIT: I posted a question to the creator on their blog and they did respond, this game will NEVER be completed due to DLSite not allowing Pokemon themed content. So yes, RIP.
