All you need to do with the green shape is get it to the outline of the shape on each level of this puzzle game. This sounds like it should be a very easy task when all you have to do is use your mouse to pick the object up and move it to the outline. The only problem is that you will have to use other objects on the board to finish your task. Sometimes you will have to use another object as a pillar for it to sit on top of and other times you won't be able to move the static object at all. You will have to use all of your logic to pass Assembler.
