I believe yes, we will have the ability to change clothes later on. But probably 1.0 once we have all the areas/clothes actually in the game.I'm not sure about Bibi's special attack, I'm not sure if the plan is to have her just as a "perk" of the city area and she might stay in the city while Chiro does her thing, not sure yet, I dont make those decisions. Shark will have his own scene, but unknown if he'll be an actual enemy. We're currently working on a different enemy type all together to spice things up a bit but its still in the planning phase.
yes josie will have her sex animation. And for the cost, I would personally do something like $24.99 based on how much we have planned, but we're probably a year away from 1.0 and I dont make those decisions so, thats just a guess.
