Aliens over the bay! Defend San Juan del Sur one key at a time.

The invaders are coming in over the Pacific, past the Cristo on the hill. Every alien carries a key. Type it and your beach cannon zaps it. You start with your left hand on the home row, then add the top and bottom rows, then do the same with your right hand. The number row and pinky keys come last. Each level adds one new key. Grab the fast-falling bonus drops, and beat the boss at the end of every row.
