update 1.2 will be out at any moment (its getting authorized by Desura), and I must say this update will dramatically improve the game. First off the building system was redesigned, every single building block was changed and new options were added, this will give the players a chance to be more creative and build things only limited by their imaginations. The best feature of the new building system in my opinion is that its corner based, this means that objects will spawn in a more organized fashion, and that they will spawn at the same level of the object you are overlaying with the mouse. But this is not it, in update 1.2 the performance increase was huge, before 1.2 i played my game at 23 fps in 720 beautiful, now I am playing at 33 fps!!. The Mac version of the game should be out at any moment as well.
