The game includes an in-game time system and "Social Networking Service" (SNS) posts to track character progress. There are multiple character-specific routes and five different endings, including one "true" conclusion.

As I journeyed deeper into the dungeon, I encountered various characters who represented different aspects of my own psyche. There was the creditor, who embodied the voice of reason and responsibility, constantly reminding me of my debts and obligations. There was the rival, who symbolized the competitive and aggressive aspects of my personality, always pushing me to be more, to achieve more. And then, there was Luna herself, the guardian of the dungeon, who represented the seductive and alluring forces that drove me to take risks and push boundaries.
