Some ideas and suggestions:
1. Players can unlock some options for villains, such as changing the color palette and the color of the back room.
2. You can buy some additional entertainment methods, which can be turned on selectively, but this will reduce or even cancel the rewards, such as: hyper belly/breast/butt (villains are almost unable to move), higher lust (immediate interaction when approached), friendly mode.
3. Optional: turn off the noise in the back room and the sound of office destruction.
4. Use money to buy a jukebox, and you can choose the music in the game to play in the office.
5. With extra money, buy mini ornaments of villains and decorate the desk theme.
6. Nightmare mode, multiple villains act together.
7. Players can even let villains work in the office... Players can chat and interact with them. I think it would be better if the game added some extra plots.
8. Change the theme of the computer, such as the desktop...
