Hundred years ago Aquatic built his little cave near by a wonderful waterfall. Every night Aquatic left his house to listen to the music of the waterfall. But one day, Aquatic faced a dangerous problem. The cave started to flood under the invasion of aqua bubbles. Being unable to stop the bubbles on his own, Aquatic cried out for help. You can become his saviour! You are in the cave, part of which is randomly filled with certain number of aqua bubbles of different colors. The bubbles continually attack in attempt to flood the cave. The complexity of the game gradually increases as you move from one level to the other: the speed of falling aqua bubbles quickens and aqua bubbles of new colors appear. Don't let them reach the water surface in the bottom. Otherwise, the cave will be buried under the water forever, and the game will be over. What you need to do is to put three or more aqua bubbles of the same color together so that they burst and disappear from the Aquatic's cave. If after bursting some aqua bubbles get disconnected from the others or from the ceiling, they fall down and disappear. For each burst aqua bubble you are given 10 points. For each fallen aqua bubble, you are given 20 points. Make sure that less and less bubbles are present in the cave. You can check how things are going by looking at a water thermometer. The more bubbles you destroy, the higher the level of water in the thermometer becomes. When it reaches the top, a level is completed. The bubbles' intrusion grows into a war with the appearance of black bubbles, which can't be burst in a usual way. You can get rid of black aqua bubbles only by blowing them up with a bomb bonus. As the game becomes more complex, Aquatic will help you by providing bonuses and warnings in case of danger. Protect the innocent creature and rescue his little house!
