They also provide a bit more context for the title:

Lead Adam, a soldier with a dark past, on a quest for redemption. Challenge monstrous embodiments of the seven deadly sins to atone for his misdeeds. Before each trial Adam must sacrifice a part of himself, resulting in a permanent debuff for the rest of his encounters.
Each battle will be more difficult than the last as every debuff lowers Adam’s health, depletes his resources or weakens his weapons and armor. Fortunately, an arsenal of unlockable equipment will help Adam compensate for his increasing weaknesses. What has Adam done to warrant putting himself through such a grueling trial" As he defeats each new boss, his history with these evil atrocities will be revealed.
