SUFFERING — is a very complex turn-based role-playing game with a unique system. Its main feature is the intricate design of the battle. The protagonist is an ordinary man who accidentally enters the Room of Suffering, and players will not be able to return to the world of mortals if they do not defeat all sinners in the Room of Suffering. As a turn-based indie game, it goes beyond repetition and adds multiple reincarnations to the traditional turn-based mechanism.
