The Game Architect of the Abyss

Soshi Kamiya, developer of the world’s best-selling survival game, is betrayed by a trusted producer and loses everything. As he sinks into despair, an email tells him that if he loves the game so much, he should stay in its world forever. When Soshi opens his eyes, he finds himself inside the game, transformed into a character from its Free Trial Version. That character is destined to die during the very first playthrough, leaving Soshi to face the world he knows as its creator.
