SpaceShips Battle app for iPhone and iPad

You specify the number of Space Ships, if you want to show a line between each ship and its target, if you want debugging information displayed with each ship, and if you want each ship to stick with its initial target or let each ship pick a target that is closest to it each time it gets control. When you select Start the ships start moving, trying to get its laser cannon pointing at its target. Each time a ship gets control it changes direction towards its target 1 degree at a time. When a ship is pointing directly at its target and is within 200 pixels of its target it fires its laser cannon, destroying its target. It will then allocate a new target closest to its position. When the last target is destroyed the game is over.
