Zipper

## Description

_Zipper_ is a fixed screen shoot ’em up. It plays similarly to other games of
its kind but instead of vicious aliens the enemies here are ordinary objects
such as flowers, apples and umbrellas. Each wave have different enemies and
they move back and forth across the screen while firing their projectiles at
the player who controls a spaceship along the bottom of the screen. The ship
has a limited amount of gas but it can be refuelled by shooting gas canisters
that at times fall from the sky. Lives are lost when gas runs out, or when hit
by either enemy fire or a falling gas canister. The player has five lives when
starting out.
