Plot

Players take the role of the captain of a river patrol ship in this top-down game. Their mission: to save the poor souls who fell into the river. In the ship's way lay boulders, crocodiles, and tree logs, all waiting to sink the vessel. The ship also has a filtration who will sink the vessel if it does not reach the dam before a time limit expires.

There are 99 levels and it takes approximately 3 hours to complete. Once you have completed the game, your patrol boat crashes into the wall of the dam.
