The Lion King, based on the famous Disney movie, is a platform game where you control Simba - initially as a young cub, and later as an adult lion. The plot of the game follows the plot of the movie. Each of the levels represents a part of the movie.
Watch as Tompa climbs walls, clones hyenas, and sticks his face in lava in order to beat this difficult game in a brisk 13 minutes.
