Lemmings fall from the sky, and go "splat" if you fail to catch them
One day, Norwegian fishermen Birger and Roald are returning home from a long day of fishing, when they spotted a herd of adorable fat fuzzy lemmings stampeding off a cliff into the ocean (as they are known to sometimes do). Overwelmed with pity and mindless altrusim, they land their boat on the beach, take up a net, and try to save as many helpless lemmings as possible.
Leaping Lemmings has been tested and is Known to work on Windows 98, Windows XP, GNU/Linux, and Mac OS X 10.4 (and should also work on any other operating system supported by pygame)
