Does anyone know how can dressing up girl and how can do diffrent sex position?
Use any Clothes Shrine, and have a first sex (POP THE CHERRIES ehm), after that she will go to the bathroom, wash herself (I don't know if you can join her, because compared to the third part, this game is very complicated even with a guide) and dress in the clothes you chose using the Clothes Shrine.
About sex positions - read the guide.
Anyway, has anyone attempted to translate the dialogue? As I understand it, it is very important in the game to understand what she is saying. The dialogue was translated in the third part, but not here.
