Little Fin Android Game Description:
The player's character is a rainbow fish traveling through coral mazes and escaping from a shark chasing it. On the way there may be various traps, predatory sea animals to avoid and dead ends from which you must quickly return.
In order to score more points, you need to swim through the rings that you meet on the way. If a small fish comes across on the way, you can eat it and increase your fish in size. This allows you to ignore some of the obstacles by simply breaking through them.
