The original Rayman was a 1995 platformer for the Atari Jaguar that was eventually ported to basically everything, including a DOS version in 1996. Rayman Redemption by Ryemanni is a reimagining of it that features “new worlds, levels, minigames and stuff to collect and complete.” It’s an extremely professional-looking project, and the full version is available now.
These days Rayman is probably just as well-known for spawning the Rabbids spin-offs as his own series. Despite having a kid-friendly tone and a protagonist only a 12-year-old could possibly think is cool, the original was a bastard-hard platformer. Fortunately for players traumatized by their memories of the Mr. Sax level, Rayman Redemption has an option for casual difficulty, alongside classic difficulty for the masochists.
