I'd love to see a few things in this game:
A different map.More locations.
More characters.
More customization.
Better environment decoration.
Feminization.
Cuckold content.
More purchasing options (sex toys, hidden cameras, etc.).
More women to interact with (with or without NTR).
Better interface.
More interaction (befriending the landlord or other characters).
That's all I'd like to see in the game for now, these are just ideas and not an obligation for the developer. I have high hopes for this game. <3
