Lode Runner is the classic Apple ][ gold-gathering platformer. This is the original monochrome Mac port from 1984, which still works except that clicking in the main window crashes the game under some OS versions (but you can still play with keyboard control - IJKL to move, UO or SF to dig, D or any other non-playing key to stop). Also includes the levels from 'Championship Lode Runner' and 'Revenge of Lode Runner', which are much more challenging.
