Objective: Rescue 2 Citizens, Rescue all citizens, Collect all Coins
Reward: 8 Coins, 80SP

Walk around the single path up the pyramid, rotating the camera around with two fingers when you need a better view. Keep going until you find the Zapper.

You can now remove Lattice blocks, so begin doing so to the mound of them next to you. This will free the first citizen, and allow you to progress further up the pyramid.

Continue up until the next wall of Lattice blocks. Remove them to free the next Citizen, completing the level.

For full completion, follow the path further around to the next coin, and the final Lattice prison. Who makes prisons out of Lattice anyway?
