My first attempt at writing a complete game limited to 10 Lines. Chosen Locomotive BASIC (Amstrad CPC) for auld lang syne. Pretty simple game many will remember from their old Nokia mobile phones in the early 2000's. Code is under 800 characters but a couple of lines squeek over 80 characters hence PUR-120. Game would easily be PUR-80 in just about anyother 8-bit dialect.
