Jim Power in Mutant Planet is a shooter/platformer created initially for the Amiga by Digital Concept and published by Loriciels in 1992. The game was also ported to Atari ST, Amstrad CPC, and TurboGrafx CD.
There is also a console version for SNES and Genesis, but the game is quite different (and much worse).
The game, designed by Guillaume Dubail and Fernando Velez, is very ambitious. The graphics are excellent, with incredibly detailed backgrounds, full of colors, despite the lack of an AGA version. The parallax scrolling adds depth to the animations, which is smooth and precise. Even the graphics of the menu are fantastic. Some people criticized the game's colorful backgrounds because they are even too much, but that will be up to you to decide. What has never been criticized is the beautiful soundtrack composed by the legendary Chris Hülsbeck. This alone represents a good reason to try the game.
The gameplay is quite original; it's difficult to decide if the title is more a shooter or more a platformer. Actually, besides the standard "run and gun" levels, there are also some pure shoot-em-up sections. Personally, I would have survived without them, but at least they add some originality.
Believe it or not, some people prefer Jim Power to Turrican. I guess because it's a bit easier to play. Anyway, now you can play both of them, and decide. Have fun!
