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.
Sweevo’s World is an isometric adventure/puzzle game developed and published by Gargoyle Games in 1986. The initial release was for 48K Spectrums although an enhanced version for the Spectrum 128K, called Sweevo’s Whirled, was also released later.
Ported by Chris Clark of Salamander Software and first published in 1984, Metagalactic Llamas: Battle at the Edge of Time is a straightforward conversion of the VIC-20 original, but with a couple of tweaks here and there.
The ZX Spectrum version of Jeff Minter‘s Traxx was published through Quicksilva in 1983. It was written by Salamander Software for Llamasoft and, to be honest, it’s not a very good game at all.
Published by Salamander Software in 1984 the Spectrum conversion of Jeff Minter‘s Matrix: Gridrunner 2 is a decent enough game, with non-flickery graphics and responsive controls. I’m not entirely sure who coded it, but it could’ve been Minter himself.
The Spectrum version of Llamasoft‘s Lazer Zone was programmed by Chris Clark for Salamander Software and first published by Quicksilva in 1983. It’s a fairly decent shoot ’em up, with a tricky dual gun mechanic to get your head around.
Headbanger’s Heaven was apparently written for the ZX Spectrum first and later ported to the VIC-20. The Spectrum version first came out in 1982 and is a pretty poor game, but with interesting character graphics and somewhat professional presentation.
