Summary: Downstream Panic is like a lemmings/puzzle cross-over with cuteness factor. The story goes that fish living in the sea were suddenly swiped up into the air. It is the player's job to return as many sea-critters to the waters as soon as possible. There are three levels within the game. However, two of them are not accessible at the time and need to be unlocked. The puzzles themselves range from very easy to very hard as the levels continue.
