Hello, you developed the 1989 version in PureBASIC:
"1989 - Pure BASIC on Amstrad CPC and not really implemented any internals. Just a selfrunning demo:"
Sometimes I read discussions on the following webpage. Those people develop games in modern PureBasic. Modern PureBASIC looks quite versatile. Oh....why not use modern PureBASIC but C to develop the current version of your game? C looks difficult.
