The early twists and the late-spike twists might feel unfair to those just entering level 19, but since it's actually a collection of the most common twist patterns, it's very nutritious. You need to be able to read and step twists of this level to handle twists in other level 19s without trouble. I highly recommend aiming for S or higher to solidify your twist skills. You can consider it the easiest among the mid-low tier.

If you can't twist, you must do this and move on.

Unlike the twists that look difficult, it's actually easier to twist than you'd think.
