If you love a fun, challenging, quirky game, you'll love this one. 3 Tiers of ten levels each...each round gets more difficult and you do them in rounds of 3. First, you're hitting worms over the head with a mallet, then you're feeding birds worms of the same color and finally you're shooting hawks out of the sky to protect the birds in the trees. Then you repeat the process with different patterns, faster moving targets and higher goals. Can you beat the the game? Have a delightful time trying when you play Birds Defender!
