At the request of rescuehero942 here at YouTube, I present to you a video walkthrough / playthrough / runthrough / etc of the Game Boy game Godzilla.
There are a ton of other stages, but the route I take (Notice how I take certain arrows when the stage is done) is the shortest to reach the end (at least according to the map I was using).
The game is rather easy once you know what to do for each stage, so there weren't too many problems. You just had to make sure you were quick enough so King Ghidorah didn't show up.
