Heat Seeker is a short arcade-like game for the Commodore 64 that was published in the March 1985 issue of the Compute's! Gazette. The goal is simple: eliminate a bunch of heat seeking missiles at a base with your fighter jet. Be careful though as the missiles can track you down and move faster than you.
In this run, nymx completes a single level of the game in record time by destroying a few of the missiles and ending input early by letting the rest of the missiles miss the jet and hit the ground.
There is also another TAS of this game by the same author that instead destroys all of the missiles as fast as possible, which is sadly slower than letting input end early.
