In Moonlights use the structure provided for you to build onto it by dragging the mouse in the direction you want to add to. Click the mouse to add to the structure, which you can make into a wheel, or a building, or anything you like. Once the structure touches the moon, your building will light up and you'll move to the next level. The moon may get higher and higher in each level which means your structure is going to have to be more sound in order to go that high. You can also play this game on your iPhone! Try your hand at a bit of physics with Moonlights!
