About This Game

Curiosity

Celestial Temple is a narrative action adventure game from Ursa Majeur. Become Curiosity, discover and understand where, when and who you are, in a dreamlike, mythopoeic odyssey across eons where each enemy you bleed wears your own face, between rage and serenity, yearning for a sliver of light in the dark of his own making.

Quickening 

Curiosity emerges from nothing already full - knees in blood, palms pressed to ash, the dark cave around him, a rib cage of old bones. No cord to cut, no cry to mark the hour. Just the wet suck of his first breath and the dark swallowing it whole. 

Törinz 

The world outside is wrong. Spires scratch at stars that don't belong there. Roman stone against humming steel. Hills hide labs where light comes from nothing. Across the flats, things drag themselves — almost walking, not quite. The tall ones wait. Three hundred meters of stillness. Older than any prayer. Watching without eyes. Crash sites. Drowned towns. Cities under cities. And somewhere below, a dark that breathes and knows how your heart is beating.

Follow the Breadcrumbs or Break it Wide Open

• Follow the questline or give in to your curiosity. 

• Find hidden paths between biomes that don’t belong, 

• Meet the characters early, 

• Steal skills from later, 

• Break puzzles that were meant to break you 

• Watch the world remember every choice you made out of order. 

Fracture Time & Space with Every Save 

Create your own world, collect the environments to place them in your own mind palace; lucid, quiet, yours, to visit old and new adventures, where you hone your skills, fly freely in your past, prepare for your next battle or try to find some small measure of peace.

All Wars Start Within

• Smell the fear, sink deep enough to never need light again or shine bright enough to blind your enemies. 

• When you can’t punch your way through, choose between Rage and Serenity. 

• Or find your sanity in between, create your own build.

• Unlock and learn new combat, utility and life skills to face the ever growing challenges. The battle inside your mind has no flags. 

La Nyctophobie 

• Each character is a mirror of you, find yourself in their reflections or carve a new. 

• Knowledge does not come freely. Every bit you grasp takes something away — a piece of you, a memory you no longer own, a thought that now belongs to the void.

• Your Rage or Serenity shapes your perspective, your relations, your existence.

• Nothing is what it seems — the monster may hold you the light, the loved ones may hold the knife. The kindness that saves you may be your ruin.

Subjective Reality

• Discover hidden knowledge, forgotten monuments, find out where, when and who you are.

• Explore six different biomes that breathe, scar, heal and shift, shaped by players choices, timing or the simple drag of hours. 

• You might find yourself in a medieval field, a tropical island or a city that doesn't exist yet — you might find yourself, literally.
