Krazy Ace Miniature Golf is a (spoiler!) miniature golf game for one to four players. The goal is to hit the golf ball into the hole in as few shots as you can while avoiding obstacles and traps.
In this movie, Aqfaq (http://tasvideos.org/Aqfaq.html) optimizes the angle and power of his shots to beat each of the game's nine holes as fast as possible. You might also enjoy reading his humorous submission text (http://tasvideos.org/4497S.html) .
