The player controls the snake's head and must make it bite its own tail located on the opposite side of the screen. In order to reach the tail, the snake must eat parchments that will appear across the screen. Each time a parchment is eaten, the snake's head stretches itsef towards the tail.
On the other hand, the player must also avoid being hit by the flying meteors who will pass through the game. Each time the head is hit by a meteor, it will retract itself, driving the player further from its goal.
The player can move the snake's head upward or downard by positioning the mouse cusor below or above the the snake's head and holding the left mouse button. The longer you hold the left mouse button, the higher (or lower) the snake will go.
