Those are all great suggestions and they would certainly make the game very interesting, though as a developer I see how those, especially the first one, would be very hard to implement.
For example, having the werewolf have multiple body types would imply having a lot of different variations of clothes to fit those different body types, and the sex scenes would have to vary depending on that factor. That would mean a LOT of work especially considering the style in which the character is drawn.
But despite that I do plan on making it possible to change the werewolf's appearance. I plan on making different fur colours and patterns for example.
