Out of This World (Another World in Europe) is a cinematic platformer that uses vector-based graphics and rotoscoped animations to deliver a minimalistic yet expressive visual style. It features a combination of action, platforming, and puzzle-solving mechanics, with a deliberate lack of HUD and textual guidance. Gameplay emphasizes trial-and-error, timing, and exploration, with a limited checkpoint system.

In 2005, a homebrew port of the Atari ST version was released for the Game Boy Advance, officially allowed by Éric Chahi to be published with the original assets.
