There are plenty of games out there that concern themselves with following the actions or adventures of marine wildlife in a number of different ways. Moby Dick and its sequel allow you to control a destructive whale that grows as he goes, and Miami Shark essentially lets you literally eat your way through the titular city.

Dolphin Olympics 2

Dolphin Olympics 2 is concerned with less destructive exploits. Developed by Alan Rawkins, the game allows you to control a dolphin and perform tricks to earn points. The more tricks you can do, the more points you will achieve, and it's undoubtedly an addictive experience.

You use the directional arrows to control the dolphin's movement. The left and right arrow allow him to move up and down in the water respectively, the upwards arrow makes you accelerate, and the downwards arrow allows you to perform a roll.

Tricks are performed by leaping out of the water and making the dolphin do various flips and corkscrews whilst in the air. Landing your dolphin nose-first also allows affords you a ‘nice entry' bonus that increases your points further. To become truly successful at the game, however, you must perform a combination of tricks and perform advanced manoeuvres by linking them all together.

The more advanced moves are performed by linking your tricks together. This is achieved by rolling underwater immediately after you land, allowing you to join your previous trick with the one that follows it by allowing it to continue whilst you are in the water.

You can also perform tricks in quick succession by simply submerging and resurfacing rapidly afterwards; this results in the acquisition of multiplier points as well as giving you a speed boost with each multiplier achieved. Tricks can range from simply flipping over in mid air to performing corkscrews, and even tail slides, which are performed by pressing ‘down' when approaching the surface of the water, causing the dolphin to essentially ‘stand' vertically on the surface of the water and make the familiar clicking and wailing sound that dolphins do.
