Bloxorz, a cool brain teaser game with a moving block

Objective in Bloxorz is to move the iron block into the hole of each platform with as few moves as possible!
There are 33 platforms to solve.
Move the block around with the Arrow keys. Don't fall from the edges, or the level will restart. There are switches that you need to hit to open or close bridges. The X shaped switches need to be hit with an end side of the block. Orange tiles on the platforms are fragile and will fall down if the block stands on it. Be careful, there are other surprising objects in the game.
