User guide

A certain monopoly-owning bad guy has been cloned hundreds of times by an unknown alien race. They are now attacking earth, kidnapping little penguinoids and converting them into mutants. Helping them on their way are some other nasty alien ships, of which there are plenty...

There are 20 levels in the game. The last level is special, with an evil boss you must destroy to complete the game.

Every time you surpass 10,000 points, one additional ship and one additional smartbomb are awarded, along with a special sound effect.

Controls

Left - Point ship left and thrust left

Right - Point ship right and thrust right

Up - Move ship up

Down - Move ship down
