K in case anyone else is wondering, there's no need to play in any particular way. Near the end of the game there's a jar you can inspect to reset your virginity and after getting an ending you are returned to just before the ending (after the fights) and can unlock all scenes after that point with no issues (in fact the biggest issue I'd say is that after that point you still need to go to dungeons to grind arousal gauge to get scenes since you can't raise it in town as far as I can tell). The art wasn't great but the scenes are pretty good anyway.
