+Waddles, your trusty pig, is ready to go on the hunt for truffles! Leash him
+up and make your way through the grove. But be warned! Digging too close can
+cause damage to the truffles' mycelia, which can take years to recover from!
+
+HOW TO PLAY:
+Select a square with the arrow keys, and press the space bar or enter to dig. 
+Waddles will tell you how many truffles are nearby by marking the square with
+a number. This is the number of neighbouring squares (including diagonals)
+that have truffles.
+
+If you select a square with no truffles nearby, the neighbouring squares will
+automatically be cleared out. If you select a square with a truffle, it's
+game over!
+
+You can use the "F" key to flag and unflag a square as containing a truffle
+without digging there. If you select a square that has already been dug up,
+and the number on the square matches the number of flags next to it, the
+unflagged squares will be dug up automatically.
