Space Invaders

How to play Space Invaders

I slide my cannon with the left and right arrow keys and fire with the spacebar. On a phone I hold the on-screen left, right, and FIRE buttons. I can hold FIRE to keep shooting.

I shoot every alien before the formation drops down to my level. The aliens speed up as their numbers thin out, and dodging their return fire keeps my three lives intact. Clearing a wave spawns a faster one, so I push for a high score across as many waves as I can.
