Sky Crane Stack

Touch a block with the bottom of the helicopter to pick it up, and then touch other blocks to link them together. Create the shape that is shown in grey, and then move it to the landing pad while avoiding the red blocks. After you deliver a shape you are shown a new shape. There are 5 shapes in total.

A keyboard is required. Use WASD or the arrow keys to move. Press the R key to discard the boxes you are carrying.
