have you thought about a nudity option in some cosmetic form, either via a reward after reaching something? Perhaps not entirely since that would mean a lot of time to rework all the CGs around it.
Indeed! Currently the idea is there will be various outfit events that change the look of all future events in the level. That way it won't take too much time to do the extra CGs. I'll make those outfit events show up relatively early so players won't have to redo levels in case they find an event before the outfit event.
