2d physics like Angry Birds

[themadanimator]

Is there some way to simulate 2d physics like is used in Angry Birds? I've tried a few things like adding a limiter so things don't fall backward or spin in 3 dimensions but not getting the results I was expecting. If I use mesh for physics shape nothing at all happens. If I use Convex Hull it sort of works but things move in odd ways. I should note that I've used 3d blocks for this but am only viewing in front view so I get the 2d effect.
