This is my new favorite game, so deep and so much content!
Suggestions:
1. A skip button for scenes that have been played before would be nice.
2. Non energy saves cost. (the diary cost is fine).
3. Functional water fountain in school.
4. Going to male or female toilet and using it, affect the (blue psyche)
5. Bench in the park for relaxing. (maybe water fountain too)
6. Brushing teeth. (The dentist must have like 5 mansions by now :D )
7. Some sort of reaction from the NPC if your genitals has switched.
