Atari Starshot

Publisher's blurb: You are flying down a trench bisecting an artificial world. A disembodied voice whispers in your ear, "Turn off your computer - BASIC is too slow." As this game will demonstrate, Atari BASIC can be fast enough if you know how to speed it up. User summary: Atari Starshot was written by Matthias M. Giwer and published as type-in source code in Compute! Issue 36, May 1983.
