In 1982, Bug-Byte published the first commercially produced games for the BBC Micro and ZX Spectrum, Spacewarp and Spectral Invaders,[8][9] both developed by David Lawson.

His second, Manic Miner, originated in a request from Bug-Byte's Despatch Manager Alan Maton for a Donkey Kong style-game.

The company had several lesser hits over the next year including The Birds and the Bees (written by Matthew Smith's school friend Adrian Sherwin[14]), the sequel Antics and the text adventure Twin Kingdom Valley which reached number one in the BBC micro charts.
