It would have been really great... if you could do anything meaningful with it. Unfortunately, you cant. Forget about making the levels like in the original game. Theres just a dozen of building blocks, only 3 of which (!!!!!) can actually be moved by the crane. This makes the whole experience awfully disappointing.
Dear author, its not hard to turn this into a really great app. Either add a WIDE variety of building blocks, or, ideally, add the possibility to design the new blocks in the app. You already have the physics engine, so its not that hard. Right now this thing isnt worth a cent. Stop robbing your fans, its very bad for your karma.
