Skydiver
Skydiver is a great three dimensional game that tests your spacial awareness. Before diving into the red paddling pool, you'll use the mouse to adjust flight direction and the tank pressure. Hold the mouse down for a longer flight or keep the pressure light for a short flight. Keep an eye on the flag because it will tell you both the direction and the speed of the wind. You may find yourself falling between buildings or going so high you hit the anti-gravity field, but don't worry! It doesn't take too long to get the hang of it, and soon you'll find yourself trying to hit every dive on the first try. How many can you make into the pool without missing?
