About

Ruby and the Lost Crystals is a calm third-person puzzle adventure where you swap between two characters with unique abilities to solve magical puzzles, activate mechanisms, and explore the ruins of a forgotten civilisation.

🎮 A solo adventure with dual-character gameplay

You control:

  • Ruby, a young girl who can physically interact with the environment: push blocks, turn capstan, activate pressure plate and jump.

  • Sapphire, a magical stone fairy who shoots projectiles to illuminate crystals, activate platforms, and swap the positions of objects.

Switch between the two to solve puzzles combining logic, spatial reasoning, timing, and magical interactions.

🧠 Evolving and varied puzzle mechanics

Each area introduces new mechanics, combined in creative ways as the game progresses:

  • Illuminate lost crystals

  • Redirect and combine coloured lasers.

  • Teleport objects to create paths and platforms

  • Move blocks and platforms to reach new areas

  • Interact with pressure plates, rotatable structures, or long-range triggers

The puzzles are handcrafted to challenge your thinking without ever overwhelming, encouraging experimentation and observation.

This peaceful third-person puzzle adventure invites players to explore two handcrafted zones filled with ancient ruins, magical devices, and hidden secrets. Through a blend of light dialogue, stylised visuals, and an evolving original soundtrack, the game offers a calm and focused solo experience built around thoughtful interactions and the cooperation between two unique characters.
