Thank you for the game; great contribution for those (like me) who live Femdom mentality as a lifestyle in a relation concept. I know that we are minority, but there is not much alternative (games) in the market for us.
I appreciate and wish that our interest and support will motivate you to develop this great idea (game) to further levels.
I would like to contribute few ideas for possible future updates:
1) To be able to edit the name of "Zoe" and "MC"
2) To be able to change physical appearance of "MC". Add more options to player wardrobe. (At least hair color, beard)
3) Add more clothes-style to Zoe's wardrobe.
4) Add more dialogues and scenarions to Zoe instead of repeating ones.
5) To change the attitude and conversations of Zoe by the increase of "Dominance" level. (Instead of lovely caring wife turning into more demanding and commanding wife) - You may change how she adresses MC, as an example not to use "Honey, my love,darling" anymore.
6) More foot worship scenes especially by Zoe's demand or order.
7) More demanding, teasing and humiliating Zoe especially when MC in chastity.
8) Could be some punishment. (As you already mentioned in your reply to another user)
In general, I really wish and hope that you could find time and desire to make some updates on this concept. I understand and accept your idea of not adding more characters, but could be easier (and less time consuming) to make minor changes and turn this game into really a n incredible one :)
