Part 51

From your starting position, fly down to a pink-topped chest and collect 60 gems.

Fly back towards where you started the level, then look left to a high platform. Fly up and charge the three metal chests for 45 gems.

Fly up to the area right of the small structure and collect another 45 gems.

The second thief will be running around the center of this area. Chase it down from the inside to catch it and get the first key.

After the first locked door, fly over the big chasm to higher ground, then fly up to the area right of the structure.

In the middle of this plain, chase the thief to get the second key.

Go clockwise around the edge of the area to find two spinner chests containing 35 gems.

Continue around the edge to gather another 70 gems.

Head towards a darkened wall on the left and fly around it. Go right a bit and fly to the green patch ahead with a locked door.

Unlock the door and a thief in a bi-plane will fly out. Go through the door, jump up the steps to gain height, and collect 45 gems on the ledge outside.

Fly towards the building ahead to find the flying thief. It will circle the building; cut the corner under the pipes to avoid them and catch the thief for the third key.

Turn around and fly over the pipes to a high platform below the flying barrier. Approach the third locked door to open it.

Jump up the steps behind the door and grab 50 gems around the corner.

The final thief will fly away below to the right, looping through the lava cave and outside. Cut corners and avoid pipes to catch it. Patience is key, especially when it restarts its loop. Flame the thief to get the final key.

Go back to where the third locked door was and enter to find the fourth locked door.

Unlock it and jump up the last set of steps to find a golden gem. Adjust your height by jumping in this room.

Fly outside to a firecracker just to the left. Flame it, then fly up and ahead to the next firecracker and flame it.

Glide left and downwards to a third firecracker and flame it.

Fly over to the chest it destroys for 60 gems.

Fly ahead of that to the last firecracker and flame it.

Fly left to the third locked door where the chest has been replaced by 75 gems.

Fly up and left to another 75 gems, then ahead to 70 gems.

Glide up and left towards the 'Return Home' vortex, but do not take it yet.

Go through the tunnel behind the vortex for 200 gems.

Enter the final unvisited room to find five explosive chests. Flame one, then stand outside until you hear them explode and collect the scattering gems.

Collect the final 950 gems in pink gem form.

Look at the portrait of Gnasty at the back of the room.

Jump into the exit vortex to finish the level and watch the final cutscene (a non-interactive cinematic the game plays automatically).
