This is a nice 3D version of the classic arcade game, Frogger. As you already know, the aim is to help a little frog reach his home by crossing the busy streets and swift rivers. But, the gameplay has changed entirely in this 3D version.
Avoid hitting the cars and falling into the river by using the arrow keys. Also stay away from the crocs and the snakes. Get 5 frogs into the caves before the time runs out, to gain points and proceed to the next level. Remember that you gain points every time you leap forward, and you lose points every time to leap backwards.
