Harley is a hip, young scientist who happens to have an IQ the size of Mt. Rushmore. While experimenting with a shrinking machine, something goes terribly wrong--the machine explodes and Harley is now the size of a bug! Harley has to find the missing pieces of his machine and reassemble it in order to return to his regular size. You'll guide him through all kinds of crazy capers, commandeering a tank, parachuting, using a jet pack, and fighting a giant rat, that will lead him to the parts he needs. When you're the size of an insect everything looks humongous.

One midget, one tacky green outfit and one hell of a game! Rosalie Newcombe (2) unrated

Electronic Arts

Though their involvement with the game's publication was tenuous, Electronic Arts did finance the game initially, evidenced by their square-circle-triangle logo appearing on the front of Harley's rocketpack harness in the cover artwork.
