Cave Fighter

Cave Fighter is a clone of Scramble, originally for the Dragon 32. Feature digitized speech at the beginning, it features the same flying through caves, shooting/avoiding missiles launched from the ground, and bombing fuel cannisters to replenish your own fuel (shown by the bar on the bottom). Tapping the joystick button fires both your forward gun and drops a bomb; holding it down drops bombs only (maximum of two onscreen at a time). One new twist is "Force Walls" which you have to shoot a hole through and then navigate through the hole.
