About this game

Earthworm Jim arrived on the Mega Drive in August 1994 as one of the most visually distinctive action-platformers of its generation. Developed by Shiny Entertainment — the studio founded by David Perry after leaving Sega's European division — it combined hand-drawn animation on a scale that seemed impossible for 16-bit hardware, an absurdist comic tone unlike anything else in the genre, and satisfyingly layered gameplay across inventively designed stages. Its immediate commercial and critical success launched an animated series and a franchise that defined the mid-1990s character action platformer.

Key Features

Hand-drawn animation with an unprecedented level of character expressiveness for 16-bit hardware; absurdist humour woven into every stage — from underwater cow-launching to blind cliff-swinging; whip-and-gun combat allowing for both melee and ranged attack styles; inventive stage concepts including zero-gravity sequences and high-speed tunnels; Tommy Tallarico and Mark Miller's energetic rock-influenced score.

The Story Behind

Earthworm Jim debuted at the exact moment when the Mega Drive and SNES were competing fiercely for the mascot action-platformer market that Sonic and Mario had defined. Shiny Entertainment's approach — large-budget hand-drawn art, a fully voiced comic aesthetic, and willingness to parody the genre itself — represented a creative left turn that distinguished the game from its rivals. The game's success demonstrated that third-party developers could produce platform mascots with the same production values as Nintendo and Sega's own first-party characters.

Tricks & Tales

Shiny Entertainment was founded in 1993 by David Perry, who had previously worked on Aladdin for the Mega Drive at Virgin Games. Earthworm Jim was their debut title, released just one year after the studio's founding — an extraordinarily fast production cycle given the game's level of visual ambition. The animated television series based on the game launched in 1995 and ran for two seasons, reaching an audience far larger than the game itself and cementing Jim as a genuine mascot of the era.
