@@ -6,8 +6,6 @@ Rows with exploded mines cannot be cleared. See how far you can get!
 Left-click to clear a tile. Right-click to flag a mine. Middle-click a number to clear any non-flagged adjacent tiles.
 
 ## stuff to add
-move middle-click functionality to left-click instead
-
 add support for mobile devices/1-button mice (probably hold down to flag a mine)
 
 save game using html5 local storage so player can come back later
