Written by Pete Cooke and published by Firebird (as a £1.99 budget game) in 1987, Brainstorm is a clever puzzle/strategy game where the aim is to draw lines using a pointer in order to make a bouncing ball travel over coloured sections of the screen, to accumulate points.
Tony Ngo‘s classic Commmodore 64 game, Park Patrol, has a decent conversion on the Amstrad, courtesy of programmer Andrew Rogers and publisher Firebird Software. The Amstrad version was released in 1986 at a budget price (£1.99 if I remember correctly).
The Commodore 64 conversion of Nightshade was coded by Shahid Ahmad and published by Firebird in 1986. It is a reasonable, if slower, version of the original game from Ultimate. What is more interesting, though, is the enhanced version, released by Nostalgia in 2016.
Amstrad Bubble Bobble was developed by Software Creations and published by Firebird in 1987. It was programmed by John Pickford with graphics by Andrew Threlfall and sound by Tim Follin.
Programmed by Mike Follin and published by Firebird in 1987 the ZX Spectrum conversion of Bubble Bobble is excellent, considering the machine’s limitations.
The Commodore 64 conversion of Bubble Bobble is held in high regard by those who know it. It was programmed by Stephen Ruddy for Software Creations and published by Firebird in 1988.
A 1986 conversion of a hit ZX Spectrum budget game, the Commodore 16 conversion of John F. Cain‘s Booty is about as bad as a video game can get.
The game constantly dumps unfairness on you, and is about as entertaining as being crawled on by a Brazilian Wandering Spider.
