About This Game

Koharu is a girl with no power to fight. In pursuit of her father's shadow, she borrows the strength of monsters and sets out for the summit of a colossal tower.

Memento Resonance is a monster-collecting roguelite turn-based strategy game centered on forging Resonance with monsters, customizing skills with relics, responding to telegraphed enemy actions, and following the trail of lost memories.

Welcome Enemies as Allies Through Resonance

The monsters that inhabit the tower are more than foes to defeat.

Offer them food in battle to lower their guard, and if Resonance succeeds, they can join you as new allies.

At the end of each adventure, choose one of the monsters that joined you through Resonance to bring back to your base and take with you on your next journey. Each monster has a signature skill unique to its species, as well as passive skills that vary from one individual to another.

Even monsters of the same species have their own quirks. Find a favorite and climb toward the summit together.

Customize Skills with Relics

Relics found in the tower can be socketed into your monsters' skills.

Boost their power, add Shield, or combine status effects with special conditions—the same skill can play a different role depending on the relics equipped. Experiment with monsters and relics to create a battle style of your own.

2v2 Turn-Based Battles Built Around Telegraphed Actions

Enemy actions—such as attacking, defending, or inflicting debuffs—are telegraphed before they happen.

Each skill grows more expensive the more you use it, while holding it back lowers its cost. With limited Mana, decide which skills to use against the telegraphed action and which to save for the next turn.

Climb Again and Follow the Trail of Lost Memories

The tower's routes and the events along them change with every adventure. Overcome battles, events, camps, and encounters with powerful foes as you climb to ever higher floors.

By restoring Memory Logs over the course of your adventures, you will gradually uncover Koharu's past and the truth hidden within the tower.

AI Generated Content Disclosure

During development, OpenAI image generation tools were used to create portions of the game's 2D artwork, including characters, monsters, backgrounds, UI elements, and icons. Suno was used to create portions of the background music, and ElevenLabs was used to create portions of the sound effects. Generative AI was also used as a drafting and editing aid for some in-game writing and localization.
