I have a couple of ideas:
1. One of the last stages will make the Main Character much younger, because of which he will start going to school. At the same time, he can go to part-time jobs.
2. Add the ability to leave the hero outwardly feminine (a girl), but return him to the understanding of who he was. It is also possible to make it so that the world will still remember him as a man, because of which he will have to pretend to be another person, this would add a lot of interesting scenes.
3. Add a purchase and choice of clothes.
4. Add more different jobs, and more scenes for them.
5. Add more characters, friends and parents, ex-girlfriends (who could ruin the life of the main character) and other characters.
6. Add more erotic and sexual scenes.
