Captain Planet and his team of five Planeteers are about to save Earth's threatened environment once and for all. You play each level as one of the Planeteers from the famous 90s cartoon, each having their own unique powers (such as creating ice platforms to jump on, or even making vines grow tall into the air which you can then climb). You even get to fly around in their own personal craft like jets and submarines, allowing you to zip around the decently sized levels. A typical mission could involve saving a number of polar bears, closing down a series of nuclear waste sites or using your jet (Geocruiser) to repair the damaged ozone layer.
Each level has a different theme based upon the team member's special power with unique puzzles to solve and several nasties and traps to avoid or destroy. Once you have completed all five levels (one for each character), just like in the cartoon when they combine all their powers, Captain Planet is summoned and finally get to play as him.
This variety of gameplay makes it refreshing back then when compared with all the other generic platforms games where you simply collect gems and find the exit.
Well as in all versions, the game here has a few major flows during gameplay. Controls are often poor. When you jump the character slowly rises, and then float just as slowly back to the earth, making the game feel extremely sluggish and hard to judge simple jumps. Also, when you lose a life your character will re-spawn straight back into the same situation without an invulnerability period, resulting most of the time into losing another life for the same reason!
The ST version offers bright and bold visuals with up to 30 colors on screen, which is rather impressive from the usual 16 colors at once for the ST computers (note that the Amiga version has 64 colors on screen here). The game here runs in flick-screen mode, which is rather frustrating. The backgrounds themselves are fine: nothing to complain about or to get overly excited about, for that matter. Colors are great whilst sprites and backdrops move fast and smooth.
The sound is also fine, having several nice tunes and SFX during gameplay (but not sampled here).
