The Nest is an amazing physics game. Help birds to reach the nest, destroy all pigs and save the birds to reach their home nest. Destroy pigs by making them collision with ground, saw obstacle or outside layout. Don’t let pigs touch the birds or the nest. Tap the pigs/birds to transform them, tap the green block to remove it, the stone (grey block/stick) can’t be removed. And tap as less as possible to get the full stars.
