From Yoshua Alvin:
Alien Math Bomber for Windows 8 is a real challenge for your math calculating speed. The world is in danger. As aliens are invading earth, you are assigned to run the spaceship to generate bombs and kill the aliens by solving math problems. Save the earth as fast as you can. Pause the game when the game is lost on focus and snapview is actived (only works in gameplay, not in main menu).
