Actually, I've already mentioned several things you pointed out on Patreon and in the previous project.
I don't prefer long-term development, so features that require heavy work, such as customization and user-mods, won't be included . Likewise, the number of large characters will be limited to two or maybe three.
I don't plan to add a futa content for this one and the stage where the player can explore inside the body is already planned.
I will add a stage for the "galley" which will act as a debug feature.
Thank you for the feedback.
