TL;DR: Shit looks wild. Yo, this actually looks like you used a program to slow down the actual game and then edited the vid back to the intended speed. Idk how you get such perfect single finger double taps like that. Maybe it's something genetic but I've been a student music for over seven years and I've loved rhythm games for just as long and I still get twitchy when I try to do very rapid tapping like that and wildly ruin the timing. Whatever it is, you're sick with it, lol.
Well, to be honest, this chart is easy. It's just that it's SOOO tiring as you progress it, which makes this a good Lv.16. Welp, time for hand exercises! =v-v=
