There was that one game, I've seen it about 5-6 years ago. It was a simple MMO, based on the LEGO bricks, not an official LEGO product; I remember one map, it was a bedroom (your character was of the lego-man size); there were some simple tools in the game, of which I remember only the hammer and some kind of a beam to move the bricks. Anyone has any idea what I'm talking about? That game was my childhood.
