Piranha King

You are an unfortunate piranha who was thrown at the bottom of the ocean(Dont ask why and how.. it is just a game). Your goal is to find the stream of water at the end of the level in order to go to less deep waters and finally get home to your river and, of course, become the piranha king! Hide under the seaweeds to avoid patroling enemies. Upgrade your speed, maximum health(Oh, yeah... You are piranha in a salty water... you lose health over time), health lose rate, boost speed and boost resis...
