This is an educational arcade game that helps players polish their arithmetic skills. The game has four master-levels of difficulty, ranging from 'novice' (which is appropriate for first graders) and 'absolute pro' (which poses a challenge even for adults). Version 2.0b fixed the bug: the ship's lasers are now displayed correctly on all displays.
