The recent (excellent) remake of The Legend of Zelda: Link’s Awakening got me ter thinkin’ about the other Game Boy classics I used to enjoy. Tiny Toon Adventures: Babs' Big Break. Bill & Ted's Excellent Gameboy Adventure. Batman.
In a not-very-roundabout way, this led me back to Super Mario Land 2: 6 Golden Coins. I used to love this game as a child, but in my older teenage years I dismissed it for being “un-Mario”, for its unusual feel by comparison to the console games. I found it terribly easy and lacking in the tight play control of Super Mario Bros. 3, or even its immediate predecessor Super Mario Land.
