Whoever said cats can't fly needs to watch this movie. Rockin' Kats is a nice platformer with tricky gameplay similar to Bionic Commando and Ninja Five-O.
This little movie represents the hardest part of the game - Channel X, which normally appears as a secret bonus stage after the normal ending. This TAS however does not play through the entire game, but inputs a password in the beginning to access Channel X right away.

This 1-minute movie has all the ingredients needed for a good TAS: high-speed acrobatics involving a punchgun and unmotivated violence towards various types of canine.

If you liked this movie, be sure to also check out the movie that beats the actual game.
