Use the "a", "w", and "d" keys to keep your fish on the screen. Collect the avocados and avoid the bones. If your fish gets pushed off the screen, it's 

Use the arrow keys to avoid the aliens and collect the coins. If you lose all your lives, it's game over. Be ready - the longer you survive, the faster the aliens come at you!

This is a two player game - Player 1 uses the arrow keys to move and the "/" key to fire. Player two uses the "a", "w", "s", and "d" keys to move and the "q" key to fire. If you collect the Power Up, you get to fire a larger missile that creates a big explosion. But watch out - you don't want to be caught in your own bomb radius! At the end of the game, you can press "p" to play again.
