When you are low on money or hearts, if you have the shovel,
just start digging in a lot of areas. This is an easy way to get $999,
and maximum amount of hearts. This will not work in all areas, but it
will work in most.
You must have at least 30 jewels for this to work. When you've only got
one heart left and you're near a save point, save the game, restart, and
load it. You'll be where you were with a full complement of hearts.
