About This Demo

🌌 Arcanum: A World of Stars and Astrology

To recover the lost light, the master and her apprentices, Helian and Oenothera, continue their training.

Under the master’s guidance, the children—and the player—learn how to read constellations by using stardust and light.

🧩 Rising Difficulty & New Gimmicks

Bound by destiny, the two children set out to find the light of the sky.

With the star clusters torn in two, each must solve puzzles separately.

You’ll need to ask your partner for clues you can’t see and share your own information—cooperation is everything.

Some puzzles can’t be solved alone, but together, you’ll uncover the constellations.

At its core, this is a game where teamwork matters—communication and deduction are key.

You can play online with a friend, or offline by switching between the perspectives of both characters on your own.
(Number of players: 1–2)

• Multiplayer mode is currently in development.

• The demo version only provides sample puzzles for single-player mode.

The puzzles provided in the demo are samples of each stage; the full game's story mode consists of three stages.

Multiplayer development is in progress, and the official release is scheduled for July.

Look forward to our upcoming release!

Since this game is designed for 2-player multiplayer, the gameplay experience may differ between multiplayer and single-player modes.

While the puzzles are fresh and fun enough in single-player mode, if you can find a friend, we recommend trying multiplayer after release.
