This is the one of the darker Choicescript games I have played. In a world where virtual reality can hijack another's senses, people use the technology to live through others: cliff diving, gorging on food, and darker things.
This game includes references to drug use, self-harm, suicide, and more. I didn't experience sexual content on my run-throughs. Each chapter has optional content warnings.
As a detective story, this is top-notch. It was nominated for a Nebula award, and its easy to see why. I've replayed it a few times and it's always fresh.
