No one speed runs this game that I know of, but I wanted to get a time for a deathless run to get the ball rolling. Think you can beat this time? You probably can! This was done the first day I had played it in about three years and I played it pretty safe throughout.
Some notes about the game: Your worst enemies in the game are not the monsters you fight, but instead the "giant horse shoe of doom" and the left side of your screen.
The horse shoe is an orange object that weaves across the screen at random and can drag you to the left side of the screen and kill you in seconds. I almost got killed by one on the very last level of the game.
The left side of your screen can kill you because Gigan can pin you against there and easily kill you with his chest saw. Other times in the game, you might get thrown back and stuck on top of an enemy and be dead pretty quickly without being able to move.
The reason I kill Mothra on each planet is because otherwise, I would have to have Mothra play through the whole planet after Godzilla already did it. It is much quicker to simply kill of Mothra at the expense of Mothra leveling down (since Mothra is never used, this does not matter). Note: If you have Godzilla move on to the next planet and THEN kill Mothra, you will see the lovely Game Over screen. It's silly, but that's how it works.
Any other information is said in my commentary in the video. I apologize for the incredibly low game volume. I mistakenly turned it off before I began the game so all that is audible is the sound from the TV being picked up by my mic.
This was done on the original NES with an original cartridge.
