Gender change is planned. Futa and big muscular are also planned. But with the "height" of the characters there is a problem related to animations. It's hard to make the animation matching the height well. For example, "hand on shoulder" animation expects the shoulder to be on a specific height. If the shoulder is higher - the hand won't move with it. Unless I spend <unknown> amount of time to make such stuff follow the height.
More roleplay stuff is also planned. It just takes time xD
