shoot'em up game for Commodore 64, 2023

------------------------------------------------------------------------------
On a distant planet, 36 Time Orbs have been placed in three zones and in 24
hours time the planet will be destroyed unless all the Orbs are destroyed.
You have been sent to the planet to save it by controlling three different
vehicles and crafts in the three zones and they are the planets surface,
underground caverns and underwater. The game is a side view horizontal
scrolling shooter where the screen is split into three parts showing all
three vehicles and crafts and they are a spacefighter for the surface,
jet-pack for the underground caverns and a mini-sub for underwater. As the
game starts you select which one to control and you move from right to left
destroying all aliens, vehicles, weapons and the orbs as the main clock
counts to zero.

As you play and you press the letter S then, when the clock for the zone you
are playing reaches the next hour, then you can select another zone to play
in. If you touch any part of the zone, aliens, vehicles or weapons then you
lose time on the main clock and you can select another vehicle to play, but
five collisions though loses time in all three zones. Once a zone has been
completed then that zone is locked and you then concentrate on the other
zones but the game is over once the main clock has reached zero. Before you
start the game, there are three difficulty levels to select and they are
Novice, Normal and Expert.
