Reincarnated as the Mastermind in a Death Game LitRPG

"Waking up in a death game with a system malfunctioning and trying to kill me was lethal enough. Now I was reincarnated as the Mastermind while posing as a player.  Logic puzzles were my element. Psychological games, rewriting reality, and a sprawling, nonexistent tower promised their share. Every player was guaranteed to live if they found and killed me, and I had nowhere to hide." Xav liked playing his cards close to his chest. He'd been donning masks his entire life; what was one more to wear? Now he's masquerading as the Mastermind of a death game that's turned against its maker, with infinite levels to climb.  Betting cards that killed you if you lost? An acting game where you died with one slip from your role? An infinite ascension brimming with clans and doors, each with their own objectives? No one had yet made it out alive. Good luck.
