This was a cool, if somewhat crunchy, tower climber. The MC fights through floor after floor of his own demons, both literally and figuratively, as he attempts to figure out how to escape Purgatory, and understand its hidden rules. Each floor has a theme based off one of the seven deadly sins. Touches on some existential ideas that I appreciated, and held my interest till the end. Even has your obligatory snarky sidekick/summon to help move the story along. The team of narrators did a great job too.
