how do you level the cumflation stat?
Since you've asked multiple questions, I'll just put all the answers in this comment:
1. Futa MC and npc:
Due to the tight schedule, I may not have enough time to add futa content— as once completed, I'll need to maintain the game's consistency with extra work for the additional gender, not just focus on a male protagonist alone. However, I'm not saying no; I just don't have enough time and am not ready for extra workload across the board.
2. Breast Size:
Yes, I think I forgot to adjust the size value based on the NPC experience. Thanks for pointing that out.
3. Anal sex is currently not available.
4. There's a limit to breast size and sensitivity; once it reaches its maximum, the bar will remain there.
5. To increase comflation experience, fill NPC to the brim, go beyond 2000ml, literally.
