Developed by Shiny Entertainment and published by Virgin Interactive Entertainment, Earthworm Jim arrived on the Sega Genesis / Mega Drive in 1994 as a platformer. It blends platformer and action elements.

It landed about 5 years into the Genesis's life. Other notable Genesis releases from 1994 include Sonic the Hedgehog 3, Mortal Kombat II and FIFA International Soccer. Among the 160 Genesis platformers in our database, it ranks #6 by legacy score.

It is part of the Earthworm Jim series; on the Genesis you can also try Earthworm Jim 2. The series also appears on other systems with Earthworm Jim (SNES) and Earthworm Jim 2 (SNES).

Earthworm Jim is a single-player game, so it's one to enjoy at your own pace.

Pick it if…

  • you want to run, jump and explore
  • you have time for an evening or two (roughly 1–6 hours to see it through)
  • you want to experience one of the Genesis's defining games

Maybe skip it if…

  • you get frustrated by precise jumps and limited lives
  • you are looking for something to play with friends

What playing Earthworm Jim is like

Platformers are all about movement: running, jumping and timing your way across levels full of gaps, enemies and secrets. The best ones feel great to control within seconds and then slowly teach you to master every leap.

Tip for newcomers: Retro platformers often have limited lives and few checkpoints. Learn one level at a time, look for hidden 1-ups, and don't be shy about using a save feature when it is available.
