## Description
In this clone of _Centipede_ , the player controls a spaceship, which can move
freely in the bottom third of the screen, and shoots upward to destroy the
oncoming snake. The snake is made up of many segments, and when a section is
separated from the rest of the body, its foremost segment becomes a head,
forming a new snake.
Scattered around the playfield are mushrooms and rocks, which can be destroyed
by the player’s shots. When the snake encounters one of these obstacles, it
descends a row and reverses direction. Destroying a segment of the snake
creates a mushroom, filling the playfield and causing the snake to descend
more quickly. When the snake reaches the bottom of the screen, it gains armor,
causing each segment to take two shots to kill, instead of one, and begins
moving upward.
Destroying a segment of the snake causes a gauge on the screen to climb. Once
the gauge is filled, the player may use a single energized shot, which
destroys every snake segment within range of the player.
Also on the playfield is a spider, which descends toward the player, though it
is slowed by obstacles. Killing the spider repeatedly will award the player an
extra life, but the spider’s speed increases each time it is killed. Its speed
resets after the player is killed, or when a new level begins.
Bonus levels appear after every third round, during which the player is
assaulted by just the spider and bees, which descend toward the player more
quickly, and are not slowed by obstacles. Like the spider, the bees move more
quickly as they are killed. After the tenth level, bees begin to appear on the
regular levels, in addition to the spider.
