Scram 20

Scram 20 is a Scramble clone for the VIC-20.

Fly a small spaceship through a system of caves, guarded by missiles. The
player has a gun to shoot down airborne targets and bombs to bomb ground
installations. Fuel supply is constantly counting down, so the player must
also bomb any fuel containers found on the ground. Later on, the game
introduces constant airborne enemies, in addition to the ground-to-air
missiles. Scram 20 utilities a character-based scroll, which means that it
scrolls quickly, but in increments of 8 pixels.
