Another great “hidden gem” on the Atari ST – Wrangler, developed by Magnetic Fields and published by Alternative Software in 1988.
Wrangler a strange isometric puzzle game, with you playing the role of a robotic cowboy called “Glint Eastwood” (groan), and who must patrol various levels, collecting a required number of coloured tiles in order to shut down some alien gates. It’s a difficult game to explain, but is quite easy to play when you get the hang of it, and also quite compelling.
