You're just clicking through text. Not even "choices" to chose from. As a simple text the concept is not too bad - the text is divided into 24 chapters, mimicing an advent calendar. As a game, it fails completely.
'Nuff said. Five minutes playtime, and being a hamster allows for some unusual and funny situations. The "intro" is a bit confusing and the parser is not very sophisticated, but the game is won before you even notice that. If I had to limit myself to one word only, it'd be "cute".
