About game
You control a fish that must swim between the rows of algae. One wrong move and your adventure could be over. The mechanics are simple: you control the swimming height of the fish. But don't be fooled by the apparent simplicity — with each passing meter, the game becomes more difficult.
How to play
As soon as you start, the fish will slowly descend. To lift the fish up, press the screen or the space bar. The more often you tap, the higher your fish will swim. There will be algae on your way, which are located at different levels. Walk between them, avoiding touching.
