Lemon Melon Cookie Full Combo!!

Is it called the diamond shape? Anyway, after I figured that out, I kept messing up elsewhere... How many tries did it take me for that level 29 song!! If you're a thumb player and finish your phone time then switch to a tablet... your wrists and arms will get destroyed... Since I haven't learned to use multiple fingers, I end up just using my index finger to move back and forth... Lemon Melon Cookie is a great song for arm workouts, isn't it(?) Thumb players, try this arm workout once(?)
