STORY:

You are a young hero named Bocco who has set out in search of treasure in the Temple of the Snakes.

Among the labyrinth of tunnels is a treasure chest that you must find. The temple is full of snakes

so be careful!. A snake inflicts damage on 1 to 4 health points. Each flask you find restores 2 health points.

Use the arrow keys to control Bocco. Have fun :)
