Help Me Fly is a puzzle game where you try to connect a battery to a toy plane to, well, help it fly. The conductive pieces come in all shapes and sizes. Some pieces can rotate and some are locked in place but most are freely movable in whatever position they start in. Each level contains a number of stars that, if you can incorporate them into the path from the battery to the plane, unlock additional levels later on. There are usually obstacles to make your life more difficult, of course, but it's pretty easy to just get the plane in the air. Getting all the stars is where the challenge comes in. It's a very solid little puzzle game and the initial download gets you a bunch of levels for free (you can buy more if you like it). Good stuff.
