The concept of the heat run doesn't really work for me. It seems more like trial and error finding out where you need to go, constantly dying because there isn't a real sense of direction on where you should be going. Perhaps a directly linear path for the game would work better. But the real issue I had with this hack is that I found myself seemingly stuck after I fell down to the area where you find the varia suit. The only path out seems to be through the Imago boss fight, but I only had 10 missiles which wasn't enough and no charge beam.
