Deadly Duck's job is to score points by blasting his enemy the Crabs, their Bricks and the Dragonflies. Deadly can keep shooting as long as he avoids getting bonked by a falling Brick or hit by a Dragonfly's Bomb.
TIPS AND TRICKS
HINTS FROM THE DESIGNER...
Practice shooting bricks on Level 1 until you can hit them fairly easily. Be careful, since attempting to shoot a brick can be dangerous if you miss. After you've developed some confidence in your ability to shoot bricks, start a new game, but this time go through the first three levels before trying to shoot bricks. Now the bricks are worth 500 points and you should have a few more Ducks in reserve.
