1. It's a possibility in combo updates. You can see who has combo updates on our website.
2. There's already a little bit of optional futanari content in the game. If we continue with any of that, it would be optional still and would be for some angels only, and it would not be trans nor dickgirls i.e. fully female + male equipment.
3. We don't reveal that kind of stuff ahead of time, so you'll have to play to find out!
Glad you like the game!
