Thanks @Crossett, this is really helpful feedback! We're planning two systems in Bangkok, which I think you'll be interested in: Suspicion and Stress.Well, I'm kind of a transformation and humiliation freak, so take my suggestions with a grain of salt. I've found I'm usually not the target audience for most games.
I think I was mostly playing through everything so far just grooming the protagonist for the mission, molding her into someone who could cope with adapting to a terrible situation.
If not for how the story pulled you along so well, I would have probably started skipping past things up until Bangkok, where it feels like you'd be getting past the point of no return. Feeling like you're on your own, with no backup or anyone to save you, so you have to start using desperate coping mechanisms to survive. Just focusing on the moment and trust you'll be allright in the end. What will she be willing to do for the sake of the mission? That's kind of what I was looking forward to...
- Suspicion is a hidden meter that measures how suspicious the organised criminals who run the red light district (and the specific venue) are of the agent. If it gets too high, it will trigger progressively worse conditions, starting with "the PC's hostel room gets ransacked for evidence" and culminating in "the Red Wa attempt to abduct and disappear her" (which will be a playable Bad End in which the PC will either survive and escape, or go MIA – either way, the game is over). Suspicion can be reduced by doing things an undercover agent wouldn't do: the idea is to give the agent an in-world reason to consider things like piercings, tattoos, boob jobs, drug use, getting knocked up, dumbing down her behaviour...
- Stress is a visible meter that increases as the agent does stressful things (like work an eight hour shift in a Bangkok brothel). If it gets too high the PC loses some control over her actions (e.g. an agent who doesn't Like Rough Sex can tolerate it if her Stress is low, but she might have an emotional breakdown if her Stress is high). Prolonged high Stress can cause her to crack under the pressure of the assignment, resulting in her being pulled out of the field (bad end). Stress can be managed with rest, but it's much easier to manage it with alcohol & other drugs. This is a mechanic to encourage the "desperate coping mechanisms" vibe you're suggesting.
