When I first started SuperNOVA, I was still in the standard/difficult setting, doing most songs and being ok… had trouble with songs like Xepher and Doll and especially Max 300…. but after about 3 months of playing on SuperNOVA at least once or twice a day, I’m moving up onto Expert/Heavy difficulty. I now play (and pass with an A or B) almost every song on Expert, including A, V for Extreme, Doll, Xepher, and Sakura… though still havent upgraded to expert on Max 300… but i can pass that with an A on standard. I’ve just started to amp up my “training” by putting the speed at 1.5x and playing several rounds without any breaks to increase endurance and eye-foot coordination. And lately, I have been listening to my favorite songs on my MP3 player, that way I have the songs completely memorized when I go to play them on Expert and so I know how the song goes and then I can put the steps in according to the music… I do a few challenges and pass, and I was even feeling confident enough to try Doll on challenge, and I barely failed, so the training continues…
