A fish and her food with many hungry enemies and you must defend her. How? By circling around many circles. It’s simple and entertaining.
In the beginning you choose one of two fish. Every level contains smaller or bigger circles with food inside. Enemies approach these places and you have to destroy them by circling around the circles. By tapping the display you gain speed and by touching the knots you get to new circles. Everything goes in very rapid tempo. The enemies increase their numbers and are more resistant.
The progress unlocks aquarium and new fishes later. The title has very catchy gameplay and interesting main content so the aquarium isn’t to motivating.
