To be honest, when I first read the title of the app, I thought this is some kind of Christmas or Santa Claus related game. But I was dead wrong... ;-p
Klaus is a free game, and the objective of the game is to keep Klaus upright as long as you can as he drunkenly tries to walk home.
According to Dr. Macenstein; I’m not sure this game has any real long term playability, but so far Klaus’ drunken ramblings have made everyone who I have showed it to declare it to be “the best thing ever invented”. ~LOL~
But hey, as long as it's free, then no body is complaning. Right?
