Hi, the player character can already go naked, change hairstyles and remove shoes. Or did you mean something else?
i always play her naked with different hair, so yes, you can already customize her. you need to go up to a mirror. one is in the starting area or you can randomly find them in the dungeon floors.
While cheating in a single player can be fun and all, most of the games attraction comes from it being a bit harder. Still, a easy mode would be nice with some overpowered items like a ring that stops KO from sex. lol. as of right now, there isnt any cheating in it unless i am wrong.
