Through which service was Rayman Mini released as a launch title?

Rayman Mini was released as a launch title through Apple Arcade.

Rayman Mini launched on September 19, 2019, as part of Apple Arcade, Apple’s subscription game service. It was developed by Ubisoft Montpellier and Pastagames and published by Ubisoft, making it one of the service’s early first-party-backed platform games.

The game shrinks Rayman to the size of an ant and sends him through a miniature world filled with environmental hazards and enemies. Its design draws on the contrast between a familiar hero and oversized natural surroundings, while retaining the series’ colourful platforming style.

Rayman Mini was available across Apple platforms supported by Apple Arcade, including iOS, macOS, and tvOS. It was not a launch release for PlayStation Plus, Xbox Game Pass, or Google Stadia; those services are unrelated distribution platforms.
