The object of the game is to eat the other serpents basically. However, you
can only eat them from behind ;) Otherwise, they eat you. Every once in a
while, you "drop" something (an egg?), and that makes you lose the last part
of your serpent. If you lose your last part, you lose one life. You can gain
length either by eating the frogs, or the eggs of the enemies. If the enemies
eggs are left for too long, a new serpent will appear. If your egg is still on
the screen when you finish the level, you get an extra life. Extra lives are
also awarded every 20,000 points. I guess that's basically how you play.

The most annoying thing about the game is when you complete a level. The
serpent will then guide itself to the lower right corner, where you started
out. The AI on this isn't all that bright, so it can actually take a couple of
minutes on some levels. I've never seen it fail to eventually get there
though, even though it can take the same path 5 times without doing anything
different.
