It looks like Travis had a little too much to drink and is a little unsteady. Haven't we all been there before..... You just move you mouse left to right (no clicking) to keep him walking in a straight line.
The object of the game is to keep him walking, without falling over, by using your mouse from left to right or right to left - you can't see your mouse which makes it more difficult.
Apparently the record is 88 meters!
And it's in German
