This is a very fun arcade game that will test your ability to handle the pressure of combat in the sky. To get started, click the Next button at the bottom right of the game's first screen. On the next screen you see, click the Start button that is also at the bottom right.
From the instant this game loads, enemy planes and missiles will be flying at you. As a result, you have to be immediately ready to go. What makes this game interesting is that instead of using the arrow keys or your mouse to control your plane, you actually use the number keys. Although this can take a little bit of time to get used to, once you're comfortable using the number keys, you'll find that you are able to control your plane quite well.
Each number key has a different movement. When you press 1, it will move your plane back and left. When you press 2, it will move your plane straight back. When you press 3, it will move your plane back and right. Pressing 4 moves your plane all the way to left of the screen. While pressing 5 won't do anything, pressing 6 will move your plane all the way to the right of the screen.
Pressing 7 moves your plane way up and to the left. Pressing 8 makes your plane go straight up the screen. And pressing 9 makes it go up and right. Additionally, clicking the space bar allows you to fire shots. Just keep in mind that while you can shoot other planes, shooting the missiles they drop won't do anything.
