I’ve just stumbled upon this advent calendar by Nintendo, where each window of the calendar hides a level of a game!

The game itself is a platform based, mario kinda game, but with a wintery look and a snowman for the main character. The game plays very well, and makes me start to wish that the Wii Internet Channel was released already so I could wake up any play the level of my advent calendar before work!
