Donkey

Donkey, often known by its file name DONKEY.BAS, is a computer game written in 1981 and included with early versions of the PC DOS operating system distributed with the original IBM PC. It is a driving game in which the player must avoid hitting donkeys. The game was written by Microsoft co-founder Bill Gates and Neil Konzen.

Directing a sports car on a stretch of rural road, the player must beware of donkeys roaming its picturesque lanes. Spot a donkey ahead and the player must quickly determine whether to switch lanes with the space bar before the car's course brings it into a messy head-on collision. With each burro successfully traversed, the car moves a little higher on the road -- closer to earning a point for the player (after passing eleven mules) but also giving less response time between the appearance of the titular donkey and its potential impact.
