Polymer Picker

Your local coastline has become polluted with discarded plastic, which is harming the aquatic wildlife. Dive in and collect the rubbish, before the fish consume it and die.

Each level contains 8 items to collect. You then proceed to the next level. The fish are initially harmless, but later levels require you to avoid the fish if you can, or they may injure you. The jellyfish are a constant menace, their sting will hurt you. Then of course, there's the sharks to contend with.

As you progress, you have the ability to swim faster. This will consume more oxygen, however. When your airtank reaches about 50%, a spare tank will appear underneath your boat. Grab it to replenish your air.

Points are earned for each item of plastic collected. At the end of a level, a bonus is awarded for each fish that is left, in addition to any remaining air in your tank.

If you run out of air, or all the fish die, then it's game over.

Although the game was written for the 8-bit BBC Microcomputer, you can play the game online. A keyboard is required in order to play it, but the controls are redefinable.
