What the developers have to say:

Why Early Access?

“LUNATHREN is a Soulslike project developed by a solo creator, aiming to grow together with the community. Early Access provides an opportunity to refine combat balance, stability, and progression while observing how players explore and interpret the castle. I believe that developing the game alongside players will lead to a stronger and more meaningful final experience.”

Approximately how long will this game be in Early Access?

“The game is planned to remain in Early Access for around 12 months. This period may change depending on development progress and community feedback. During this time, the focus will be on improving gameplay systems and expanding content based on player input.”

How is the full version planned to differ from the Early Access version?

“For the full version, I plan to expand the castle and introduce new story content beyond the current areas. Additional bosses, weapons, and moonlight abilities are being considered.”

What is the current state of the Early Access version?

“The current version includes three boss encounters and four castle zones, with fully functional systems such as saving, inventory, combat, and dialogue. Core cutscenes and story sequences are implemented, offering around one hour of stable, playable content.”

Will the game be priced differently during and after Early Access?

“The current plan is to maintain a stable price during and after Early Access. However, minor adjustments may occur in the future depending on development costs or content expansion. Early Access players will receive all future updates at no additional charge.”

How are you planning on involving the Community in your development process?

“Community feedback will play a central role in improving combat balance, map design, and accessibility. Players can share suggestions through the Steam Community, Discord, and regular surveys. Development updates will be shared weekly or monthly to maintain transparency throughout the process.”

About This Game

“In a castle without moonlight, longing is born.”

LUNATHREN is a 3D Soulslike Action RPG with gothic and ethereal visuals, offering dense exploration and combat within a single, massive castle.

You awaken as an outsider in a sealed room, seeking to bring the white moon—a symbol of freedom and hope—into the castle by breaking its seals. Along the way, you face warnings, betrayal, and traces of longing that challenge your resolve, as the boundaries between dream and reality, light and darkness, begin to crumble.

When the moonlight finally reaches the castle,
what will you see?

Key Features

  • Soulslike Combat
    Precise stamina-based combat focused on dodging, parrying, and striking.
    Unleash the power of moonlight to acquire and enhance silver-lit abilities.

  • Metroidvania-Inspired Exploration
    Progress by unlocking previously sealed areas within the interconnected castle.
    Experience the thrill of discovering new areas and hidden secrets as you expand your path.

  • Dreamlike Storytelling and Visuals
    Short vision-like cutscenes appear as you break seals, blending dreams with reality.
    Gradually uncover the forgotten truths and the meaning behind the white moon.

“When the silver moonlight touches your fingertips,
what shadow will this castle leave within you?”

Prove your longing in LUNATHREN.
