Click on groups of 3 or more similar-colored pearls to make them disappear. The more pearls in your chain when you collect them, the higher the score value. Click on groups of 3 or more clear bubbles to gain oxygen. If you run out of oxygen, the game will be over. The game also ends when pearls reach the top of the game screen. Controls: Use the mouse to move around and left mouse button to click on pearls.
