🌌 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.
Play with a friend and take on the challenge together!
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.
