Chuckie Egg is a platform game released by A&F Software in 1983 initially for the ZX Spectrum, BBC Micro, and Dragon 32/64.
It was ported to the Commodore 64, Acorn Electron, MSX, Tatung Einstein, Amstrad CPC, and Atari 8-bit computers.
After a month or two of development, Nigel took a pre-release version of his Spectrum code to the two-year-old software company A&F, co-founded by Doug Anderson and Mike Fitzgerald (the "A" and "F", respectively).
Doug took on the simultaneous development of the BBC Micro version, whilst Mike Webb, an A&F employee, completed the Dragon port.
In addition there are piles of seed which may be collected to increase points and stop the countdown timer for a while, but will otherwise be eaten by hens that patrol the level, causing them to pause.
Available on a much smaller subset of platforms, this release changed genre quite radically and involved the player, as Harry again, working through a factory attempting to create Easter eggs complete with toy, in a Jet Set Willy-style adventure.
