The basics of the game are done; mining and collecting items is possible, destroyed walls will drop rubble and (in most cases) ore of a certain sort, player score increases by collecting certain items,
the map border can not be crossed any more, 'p' pauses the game, main menu shows a few button commands, objects and object types support multiple images now, some player animations have been added.
Addition: To mine, walk towards a wall and hold 'ctrl' for a few seconds.
