The map data structure is simply a 2D list of lists where the two indexes used represent the X and Y coordinates of the map. The value at each index in the list of lists is a single-character string that represents the title that is on that map at each space:

'#' – A wooden wall.
'x' – A corner wall.
'@' – The starting space for the player on this level.
'.' – A goal space.
'$' – A space where a star is at the start of the level.
'+' – A space with a goal and the starting player’s space.
'*' – A space with a goal and a star at the start of the level.
' ' – A grassy outdoor space.
'o' – An inside floor space. (This is a lowercase letter O, not a zero.)
'1' – A rock on grass.
'2' – A short tree on grass.
'3' – A tall tree on grass.
'4' – An ugly tree on grass.
