It took me about 3 minutes to figure out SJF on GC, because I had already figured dash jumping out and was just using it for shits an gigs until I saw that and was like ZOMG
It took me about an hour to get SJF my first time. I still remember the first time I saw space jump first. I was in complete awe because I had never seen Metroid Prime played that way. It was only about 5 months ago but I have really come a long way. I can't believe there are still people complaining about how it's impossible. They must really, really suck.
