I think this is the best game ever for the old black and white Game Boy. The graphics are great for Game Boy there are seven different levels that you must complete to and get golden coins before entering Wario's Castle and fighting him. There are also hidden levels. You can save your game. You can save up to three different games. If you have Game Boy Color it interprets the black and white into some color pretty well. This is a great game if you see it for sale somewhere used.
