Can you stop the invasion of space invaders?

A twist on the classic bubbles/marbles matching game, Invasion sees you shooting missiles up at a horde of descending space ships. You can destroy the invaders by matching three colors or shooting a special missile such as a nuclear bomb, wildcard or the black missile, which destroys almost anything.

Higher scores earn you nuclear bombs and wildcard missiles to fire at your request, and these rewards stick with you even if you lose the game.
