The trick is just set up all your defense on the left side, then uproot and move them to the right side, then I think left side again. By that point you should have at least a macro hatch and full harvest saturation, and can build enough to defend both sides pretty solidly. Don't even start building offensive units until you're saturated. About 5-6 swarm hosts, 2-3 spine crawlers, and 2-3 queens on each side will keep the entrances on lock down, then just mass mutas to help wherever its needed. You can also try to grab the expo fast; The enemies ignore it most of the time, and the few units that stray over there can be picked off with your mutas or a few extra spines/spores.

Once you're impenetrable, you can fly your flock of mutas down to kill the tyrannosaur(?).
