This requires it. Well, specifically, requires pressing down to charge a spark and up to jump in about a frame, to get to a point where you can use the spark to break through a barrier before the charge wears off.
i like to think of it in terms of that number after the seconds on a stopwatch. if you did down+up every two frames over and over, you would do it (down+up) three times each time that number after the seconds changed.
Even though it's mine and Zeke's fault that the topic is specifically about RockPaperScissors right now, I'm going to blame it on The Dark Knight for randomly asking how to open his GameBoy.
I have like 10 bucks credit at EB, and low% ZM is kinda driving me insane...I am dangerously close to picking up this game. Of course, I doubt getting the Secret Message will be any easier than getting out of Tourian alive.
