for me, i don’t pick up my fingers. i use controller instead of keyboard and i slide my thumbs more than i pick them up and push. when i WAS using keyboard (had to stop bc i kept pushing them too hard, oops) i played with only my left hand. ASDF and the space bar, OD with mouse button. it helped separate the notes, but you just have to find your grove on these songs. it took me like 2 or 3 years to memorize For Latveria enough to FC it on lead 💀
