I'm just gonna let this go a few more updates before trying for it. Once it's up to where the first one was at I hope he picks up where it left off. AFAIK there was still more that was planned for it but never completed. I think the game still has a lot of potential. Lots of room for intriguing stories.
If the game could end with Billy becoming world dictator with a massive harem, or world guardian a la Superman, also with a massive harem, taking out rivals and mind controlling foes to get there, I would love it.
Maybe an option to transform other characters. I know transformations are work intensive, you have to have a separate model and scene for usually scenes that are already done, we get this with the Billy -> Billy Jean thing, and all the clothing changes. But I think it would be great to be able to do that. It could be as simple as giving a girl bigger tits or maybe Billy finds out that there's a girl that doesn't like a part of their body and he is able to change it. Turning guys into girls could be an option too.
One of my favorite H Game scenes was in Harem RPG where your given the choice to transform and enslave your rival or order one of your harem to execute him. I chose to kill them but I thought it was a really great story element. It was like, you do not deserve to be one of us. It was a really evil character and they deserved death, it was just metal AF.
Maybe Billy could meet a villain(s) that causes him some real grief and he has to decide to enslave, selfishly kill, or righteously enforce justice.
