Take charge of space traffic control on a series of busier and busier planets and space station whilst constantly scanning the skies for comets, asteroids and other passing traffic!

Guide the saucers to the landing pads by clicking on them and dragging a flight path. Use the PLAY and FAST FORWARD buttons to change the game speed (the first few levels are quite slow).

There are items to buy which rewind time, cancel certain kinds of collision or land everything on screen automatically (the Panic Button), but the game can be played and completed without them.
