Players explore towns and dungeons from a first-person perspective, moving through grids, doors, traps, and encounters. Battles are turn-based, with commands for physical attacks, guns, spells, items, defense, and Persona changes.

Personas determine each character's available magic and strengths. Players can negotiate with demons to gain spell cards, then use the Velvet Room to fuse cards into new Personas. Formation, weapon range, elemental affinities, and the Moon phase affect encounters. The main route progresses through story dungeons, while the Snow Queen Quest provides a separate, more difficult campaign with its own progression and party structure.

Build a balanced party instead of relying only on physical attacks. Keep Personas with healing, elemental coverage, and status resistance, and pay attention to enemy weaknesses before committing to a long dungeon run.

• Negotiate regularly to collect spell cards and fuse stronger Personas.
• Save before major story choices, especially those connected with the Snow Queen Quest.
• Carry healing and status-recovery items; dungeon attrition is a greater threat than many individual battles.
• Check weapon range and formation, since a strong attack is not useful if the target cannot be reached.
