State-of-the-art scrolling techniques allow for 4X the space! Simply click and drag the screen to shift your view. Click and drag a building to move it. Press SPACE over the factory to make little creatures appear and head toward the tent. Very buggy, though -- if the creatures head the wrong way try moving the tent.
