Finally perfected Saihate on Extreme.
It is a unique song with lots of double-tap notes. Fortunately I have listened this song to death, so it doesn’t take long for me to figure out some patterns of the ‘cute beats’ sections; e.g. the in-between sets are always the same with just different buttons to press, the last set is the same as the in-between set plus an add-on, and the set of 4 double-tap notes is a circular rotation.
The hardest part, I think, is to get my thumbs to react properly when I see the double-tap notes. Once I’m used to it, it is not too difficult. I still used 5 help item chances on my last try, though – there were a few screw-ups I managed to save myself from… :p
p.s. Before playing this song, I was actually playing Migikata no Chou, as LittleV suggested. The song really got easier after I played Promise, but the instrumental part was still tricky… and the thing about me who don’t have much rhythm gaming experience is that I don’t have the stamina to quick triple-tap and quadruple-tap button constantly, so I gave up on the song after dozens of tries for now… and went to Saihate. I shall attempt it again next time!
