All you have to remember to get your serpent safely through the cave, is to press and release the mouse button. Sound too easy? Go ahead and try it! The game starts off at a moderate pace to allow you to get the hang of it, but everytime you earn 400 points your level increases. With every level increase there is also an accompanying SPEED BOOST. This game is easy to learn and makes for hours of fun... o.k. maybe minutes, but it will kill some time and break up an otherwise monotonous day.
