Thank you so much!
Also good question! Growth stuff is going to be determined by the player's choice of Sin. Later in the story they'll find a shrine that they can desecrate to embody one of the Seven Sins, which essentially acts as a kind of prestige class with additional stat increases and abilities.
Wrath will focus on muscle, Sloth on butts, Lust will have pregnancy and breast expansion, and so on. I'll make sure that each sin description
tells the players what kinds of kinks they can expect.
There'll be multiple shrines to desecrate, each providing a boost to power and respective growth when you reach them! I'm considering the
the idea of allowing a flat boost to stats for players who want to commit to a smaller size.
