Does anyone know how to level up? For that matter, does anyone know how to do anything at all? I see two ways to go from the main area, but going through the crystal cave thing I get stuck at a locked door overlooking a red area at the end of that shota camp thing and going to the other place I get stuck at the cliff area. Both just seem like dead ends to me, but especially with the crystal cave it's hard to say--it's so labyrinthine I could be missing a lot. Does anyone have any ideas about what to do in this game?
