FPGA Games: Frogger

  • Frogger was a product of the popularization of "cute" games throughout 1981 that moved away from alien and explosion themes. In the game, you must direct a frog through traffic, and across a crowded river, and in to one of five enclosures at the top of the screen. Frogger isn't credited with many innovations, but it did break ground in continuous background music that changed contextually based on the action in the game.
