Dolphin Adventure

Dolphin Lucky must find the precious black pearls in the intricate labyrinths of underwater caves and then return to the surface. Collect white pearls to score more points and to fill health. The dolphin can't do without air too long so it is necessary to rise to the surface in time to make a breath or to look for air bubbles under water. The Dolphin should be afraid of underwater inhabitants: jellyfish and crabs, sea snakes and octopuses, electric stingrays and toothy sharks. Use sonar to destroy enemies.
