It's been on my mind for a while now. Your renders are well done but I was wondering if you could add more liquids for cum facials and leaks in during sex scenes? My opinion is that there could be more 'cum volume' to go along with large organs for facials, breasts and pretty much ejaculation in every hole. Kinda off-putting with that juxtaposition of so much and so little especially when everyone is designed to be bigger since that's the fetish here. Sorry if I sound rude.
Another great way to minimise workload could be to just make scenes specific with current states such as preg tiff having a fixed set of scenes instead of a variation of base scenes. Preg Tiff only scenes and Non-preg Tiff only scenes where both cannot be chosen regardless of Tiff's current state. Infected and living characters could also be limited to certain sex actions to cut down on the need to go back and remake renders again for a whole new body shape.
Moreover, the number of variations with body types may escalate into more work required for renders. For now, I think it would be easier to just have new Tiffany preg and non-preg without adding different sizes. It's pretty much multiplied alongside the many choices driving the plot where you have to render for a lot of them. This is only abt Tiffany and not including any potential side characters for optional body changes. The previous scenes existing will then have to be remade so that's extra work made unintentionally. I'm actually worried abt how you're coping with such a future large project with branching plot lines. It's a burden when the number of things to do rises exponentially with each branch. Take care of yourself and try to keep the story as linear as possible(Srsly I get the feelings of stress and mind boggles from the amount of images I've counted so stay healthy aight?) This game has so much potential and can be overwhelming on where it should head into storywise.
I can't give any opinions about the plot and its contents, but it would be more easier to produce scenes without ever having to remake it twice again everytime tiff or somebody else goes through a change.
Now just as a side note, I do have questions. Will future content ever have dominant female characters if any and in whatever form?
