Zorya: The Celestial Sisters

Project Zorya is a two-player asymmetric cooperative puzzle game. Each player plays as one of the two Zorya sisters: Solveig, goddess of the sun, or Aysu, goddess of the night.

When playing as Solveig, you have an overall view of the level, allowing you to guide the other player around the level and solving macro elements of the puzzles. Your principal task is to help your partner navigate around the level by moving the position of the sun in the sky, shifting the shadows around. Unlike your sister Aysu, who is vulnerable to the sunlight, Solveig is protected from retaliations and is invulnerable. You must assist her with your sunray, a visible beam of light casting a spotlight on the ground, which can stun the enemies on the ground when they are inside it. Your sunray allows you to also interact with diverse activators and other puzzle key elements.

If you choose to play as Aysu, your camera is over the shoulder and you must navigate only in the shadows, the sunlight being fatal to you. Your partner's light shift will create new shadows and allow you to reach otherwise inaccessible areas. Dark places being beyond reach for your sister, you must communicate and resolve micro puzzles to reach the end of the level. These puzzles can only be completed by using Aysu's wind powers to move and activate elements in the environment. These powers can also help you to push around enemies. By pushing them in the sunlight, Solveig can stun them with her sunray and give you a break from their incessant attack to push you in the sunlight.

Your goal together is to lead Aysu to the end of each level to capture a lunar artifact, so she can regain her power, without stepping into the sunlight. The game is completed when all lunar artifacts are found.
