Quite a popular office game Bloxorz - NextCool

Bloxorz is an incredibly fun mini-game introduced to me by a friend. It's apparently all the rage online right now. And according to some sources, only four people in the world have managed to complete all the levels. Essentially, it's a puzzle game similar to Sokoban (the box-pushing game). Made with FLASH technology, it features top-notch sound effects, simple and intuitive controls, but it will definitely put your intelligence to the test.
