If you find that some of the elaborate tower defense games are bit too eye glazing and forbidding to get into, then this cute and simple game is a great place to start.

Chick Chick Boom is a combat-style game that pits two teams of chicks against each other in a small divided field. Draw your attack and defense moves on an egg at the bottom of the screen and try to best your opponent. Chick Chick Boom also holds the priviledge of being one of two Flash games to be sponsored by Nintendo.

An absolutely gorgeously detailed 2D side-scrolling platform Flash game with production values that rival Nintendo's own offerings in the category. In fact, this one appears to have been commissioned by Nintendo as an advergame as it contains all sorts of delightful unlockable goodies—from screenshots and wallpapers to videos and ringtones—from several of Nintendo's latest DS handheld and Wii console offerings.

You don't have to live in Australia for the latter.
