SF Cave is proof you don't need manuals as thick as a Tom Clancy novel, or controls that need four sides of A4 paper to get moving. With one key (thrust), SF Cave will take you into the Danger Zone of addictive gaming. Originally written by SunFlat (hence the SF), this Symbian OS conversion by Ewan Spence and FreEPOC shows you don't need fancy graphics and depth - you just need a good idea.
