I own a copy of the regular edition from the Ebay sale. I have beaten it, but unfortunately it has been over 5 years so it is hard to remember any details. It is a very difficult game in the later worlds. I think there was about 6 worlds and a final boss that is comparatively easy to beat and should only take a few tries at most. He is the moon character you see at the beginning. I can make a small contribution to this thread, a picture of the end screen. Because of this thread I'm going to have to play through it again, I'll try to take some more pictures this time through. This is one of my favorite NES games including commercial releases, he is such a talented developer I really wish he would release another game. I talked to him a few years ago and he said he was developing another game so you never know, but I think he is likely one and done.
