"20 screens * lifts * 21 aliens * spikes * music * demo mode and lots more. Great graphics leap about that is just so neat...By 'Hunky' Peter Scott."
It's easy really, just collect all the valves on each screen and make your way to the door at the bottom of the screen. You can fall any distance wihtout dying and you can kill the aliens by pressing the 'shield' control. Careful though, this uses up your energy.
To play the game, follow the screen prompts. Select sound on/off and then press space bar. We are told CTRL/C does strange things but we'll leave that up to you.
Z - Left, X - Right, * - Up, ? - Down
