Very nice retro style, only problem I had with it was I couldn't figure out how to select game B, as pressing K on the menu just brought up the credits.
Well, when you boot up the game, you're not on the main menu, you're in the tutorial. There's text on the board that says "Press A to Close", at which point you've closed out of the tutorial and are on the main menu. At that point you can press K to play Game B :)
