Punctuation Invaders is an arcade grammar game pitting the player
against extraterrestrial invaders in the form of unpunctuated,
uncapitalized sentences. The student fires a laser to punctuate words
while avoiding shots from the alien. But the sentence must be
completed before the aliens get close enough to beam up a human.
