About MementoMori

MementoMori - about the game

MementoMori is a free to play RPG that combines idle progression with gacha character collection and narrative focus on a world of witches facing persecution and curses. Players assemble teams of these characters to advance through an automated combat system while building resources even when offline.

Gameplay

The core loop centers on full auto battles that run without direct player input during fights. Teams of five characters engage opponents in turn based sequences where skills and attacks resolve automatically based on equipped abilities and stats. Live2D animations bring the characters to life during these sequences with fluid movements and expressive details.

Progression relies heavily on the idle system. Characters continue to earn experience and materials while the player is away, allowing steady advancement without constant sessions. Gear enhancement plays a key role in customization, as players refine equipment to adjust growth paths and optimize performance for specific team compositions. Strategy emerges through careful selection of characters whose abilities create synergies, rather than real time commands.

Character stories unfold alongside gameplay, revealing backstories tied to the central conflict involving the Church of Longinus and the Witches of Qlipha. Each girl features a unique lament performed by notable artists, integrated into the audio design to deepen emotional context during play.

Game Modes

Main quest progression forms the primary single player path, advancing the overarching story through sequential stages cleared via the auto battle system. Additional modes expand on this foundation with varied challenges that still use the same automated combat resolution.

Guild features allow players to join or create groups for cooperative elements and communication. Raids and guild related activities provide opportunities to tackle tougher encounters alongside others. PvP modes operate through league style matchups that tie into guild standings without requiring direct competition outside scheduled events.

Endless tower and roguelike dungeon options introduce repeated runs with buff selections and roster management under constraints like limited lives or gauntlet structures. These modes reward incremental improvements from idle gains and gear upgrades while testing team viability across multiple encounters.

Story and Presentation

The narrative follows ordinary girls granted extraordinary powers who become targets during widespread calamity. As curses overrun nations, these witches pursue a path of resistance framed around themes of justice and fragile hope. The tale expands through individual character arcs delivered via voice lines and dedicated songs that reflect personal emotions and fates.

Visuals emphasize detailed character designs rendered in Live2D for battles and menus. Audio stands out with a soundtrack that blends orchestral and vocal tracks performed by established artists, supporting the somber tone without relying on standard game music conventions. Players can switch between English and Japanese voice options in settings.

Is It Worth Playing?

MementoMori suits players who prefer passive progression and high production values in art and music over hands on combat mechanics. The idle and auto systems deliver consistent advancement through story stages and side modes, while gacha collection and team building provide long term goals. Steam user reviews rate the PC version as mostly positive, highlighting the soundtrack and character presentation as standout elements.

Those seeking active real time battles or complex manual controls may find the automated nature limiting. The game remains supported with ongoing content updates focused on new characters, events, and guild features. Availability on PC makes it accessible for sessions that fit around other activities, rewarding consistent logins with steady power growth and narrative reveals.
