About this game

The developer's description, from the game's Steam store page.

On the brink of collapse in the world of Lunarium, two girls—Ave and Lune step forward.

To save their dying homeland, they embark on a perilous journey into the unknown. Across multiple worlds, they must overcome countless trials while piecing together the ancient secrets of this realm—and ultimately uncover the truth hidden within themselves.

Play as Ave, a light-armored knight, and journey alongside Lune, a flaxen-haired girl with mysterious powers.

Together, they set out to save a world on the brink of collapse. Sword and magic echo between them as they fight side by side, weaving a bond that belongs to them alone.

  • Ave

An agile knight skilled in close-quarters sword combat. With precise dodges and well-timed parries, she turns enemy attacks aside and strikes back. She is the party’s blade — and the one who stands at the front when danger closes in.

  • Lune

A girl who wields mysterious magic. She can weaken enemies, enhance Ave’s attacks, and break through obstacles in the environment. She is an irreplaceable source of support — and the key to moving forward.

Players can adjust Ave’s combat style through Embroidery, the Skill Tree, and Cloaks, building a flexible progression system for different ways to fight.

  • Cloak System

Cloaks offer both unique appearances and ability effects. Players can choose different cloaks to match their preferred way of fighting.

  • Embroidery System

Embroidery works like charms, each carrying a different power. Equipping them grants Ave passive enhancements that can support different combat styles.

Step into unguarded temples, the ruins of fallen kingdoms, and churches shrouded in dark mist. Each area has its own atmosphere, terrain, and combat rhythm.

Explore forgotten lands, observe your surroundings, learn the mechanics, and press onward through a journey filled with danger.

"Our journey begins with parting, and perhaps it will also face parting in the end. The hardships along the way will surpass your understanding and imagination... You might even feel pain because of this."

"Even so, will you still come with me?"
