The fact that Miplezur is not only the largest planet, but also has by far the strongest gravity should be a hint that this is not a fun place. Fortunately the enemies aren't very numerous and most areas are fairly wide open, so you only have to really worry about the gravity. The planet has three different sections: at normal surface/underground, an underwater section, a final cyberzone-like area. Because you really don't need money at this point, and very shortly in won't matter how many lives you have (more on that later), so I'm only going to give directions Fuel Cells.
From your ship fly out and to the right, then head underground into a tunnel. There are two side tunnels, the first leads to a crystal and the second is the long way to the final section. Ignore them and continue to the right until the tunnel bend upward and then dumps you into a large chamber. Head all the way to the left and then follow the wall upward. Fly past the small wormhole and continue upward until you reach the end where a Fuel Cells rests. Take it back to the wormhole and then fly through.
You will now be at the top of a large chamber. Head down, into the water, and head right. Eventually the tunnel will narrow and bend upward. Once it levels out again fly along the bottom to find a pit with the second Fuel Cell. Take it back to the wormhole and then follow the ceiling from the wormhole to the left. Continue following it as you fly left, then up a small shaft, and then to the right, which leads to a chamber with another Fuel Cell.
Take it back to the second wormhole and then fly through it to get to the right side of the planet's surface. A short ways to the left of the wormhole are a couple of armored gunships and the final Fuel Cell of the game. Take it back through the worm hole and then go through it to end up in the underwater section of the planet.
The good news is that you are actually at the end of the water section, having used the worm holes to completely bypass it. Head left a little ways and then right as you get to a spare ship you will see an opening where the ocean floor opens into a humongous Cyberzone-like structure. The section is a maze that leads to the large wormhole and the final stage of the game. The solution to the maze can be found here:
Basically what you need to do is head all the way to the left and then down to the bottom. Once in the bottom left corner of the maze make your way to the right until you are directly below the large wormhole and fly straight up and through it.
On the other side of the wormhole is an extremely large chamber with two ridges sticking up from the bottom. You enter on the left and the final piece of the Golden Warpship is on the right. Make your way through fighting past the gravity balls and gunship spawners, navigate through the narrow passages, and get to the piece of the Golden Warpship. As soon as you get the Piece into the small wormhole you automatically begin the final flight sequence.
