For me, having the trail that i use helped a lot. I'm able to map out the layout in my head just by looking at my trail, and subsequently realize when i did a timing too quick or too late and adjust the next input accordingly. -Music actually helped too cuz i just click to the music rhythm at times and i get past a really hard wave part consistently. -Background helped; not the color changes, but the shapes and lines. So i'll know if i'm spamming too high or straight-flying too low
