Serpentine
arcade game for Commodore 64, 1982

------------------------------------------------------------------------------
Push [F1] to start the game!
In Serpentine you control a multi-segmented snake in a maze; your goal is to
survive and earn as many points as possible. At the beginning of each level,
three enemy snakes will also enter the maze. To complete the level, you need
to eat all of the enemy snakes. If an enemy snake has more segments than your
snake, you can only eat segments that form the tail of the snake; a collision
with the head is lethal! Each time you eat a segment, the enemy snake will
become smaller until eventually you can devour it completely. For enemy
snakes that have fewer segments than you, you can eat the tail segments or
the head segment. From time to time, a frog will appear in the maze; eating
this will cause your snake to grow. Both your snake and enemy snakes will
leave eggs behind occasionally; left alone, these will hatch (your eggs earn
you an extra life, enemy eggs will hatch another snake). Eggs can also be
eaten to remove them from the playfield, so it's usually a good idea to eat
enemy eggs before a new snake hatches! The maze changes for each level, and
the enemy snakes progressively become larger and tougher to catch.
