Thanks for ask, I forgot to add the notes for the codes in the game help there are:
Ma-Male Fe-Female Di-Dickgirl
Fu-Futanari MC-MaleCuntboy FC-FemaleCuntboy
Cuntboys are: Males with vagina and in this game females without breasts too.
At the street you can accelerate the time till a client with the gender preferences appear, I'll add the option to send a worker instead of you in the nexts versions thanks for the suggestion.
1-To savethe game you can open the menu with the S letter in the keyboard and go to File>Save.
2-Pressing the F1 will show the game engine options where you can activate/deactivate the fullscreen mode, I will add the option to make it in game.
3-Yes, the avatar is generated randomly for fast start but you can personalize your avatar and preferences at the start of the game: after the introduction question, you will be asked if you want to personalize your avatar, you can go Personalize>Likes for choose a max of two genders, before you can add more by training.
