Live is hard at least at this game. As fish, you must kill another fish in order to stay alive. To win this game you must click your mouse in front of your fish. This action will makes a bubble heal your fish. Beware with the sharp thorn, it can decrease your health. Click the water to make a ripple so the fish swim away from it. Killing enemies gives you cash which you can spend on upgrades such as shotguns or ion cannons for your cute little fish. Good Luck!!
