Featuring the 4 most popular methods of doing Kiss-Kiss, updated for the patch that made the one finger method harder. This is also "breaks" the Cross-Uncross technique because it requires a much more accurate motion to consistently register all 4 slides in a kiss without breaking.
(For info, the thing that the patch changed was the ability to register the notes that come after the current note. After the patch, you must register all notes in a lane in sequential order, that means that you must register an inward motion before an outward motion for kiss kiss or you'll drop one of the 4 flicks)
