The interview describes how LLM-driven characters remove fixed puzzle solutions, making each playthrough, and each streamer's commentary style, generate different escape routes.

AlterStaff released AI2U: Last Together Until the End ~Yandere Cat-Ear AI Girlfriend for PC and Mac on August 13. The escape adventure pits players against yandere characters driven by large language models, who react in real time to spoken or typed dialogue. The game is available for 1,700 yen, with a 30 percent discount to 1,190 yen until August 27.
The developer behind the yandere escape game AI2U says the characters players flee from are not scripted. They run on large language models, and the dialogue input, typed or spoken, changes how each stage plays out.
Wengu "Eddy" Hu, founder and CEO of AlterStaff, described the project as starting in 2023 as a free prototype called Yandere AI Girlfriend Simulator, built with his wife Vivianna Yan in about three weeks. That itch.io release has been downloaded over 1.3 million times.
In AI2U, players are kidnapped by characters including a yandere girlfriend, a cat girl, a witch, a hologram space girl, and a siren. Escaping means finding a way out or negotiating freedom through conversation, with no fixed linear solution to any room.
