Thrust (GEM)

How many of you remember Thrust on the C64, Spectrum and others? This is the ST version and it runs in a GEM window. For those unfamiliar with the original, you control your spacecraft in a similar manner to that used in the game Asteroids (except there are no asteroids!) and must avoid crashing and being hit by enemy fire. The goal appears to be to destroy the other spacecrafts and find a ball located somewhere within the level. Reaching the ball results in completion of the level. Only one level is supplied but you can make up more using any monochrome graphics package and a text editor.
