Every slider must have a clear and visible path to follow from start to end. Sliders which overlap themselves in a way that makes any section unreadable or ambiguous (including "burai sliders") cannot be used. This is so that no slider has an appearance that is confusing or impossible for the player to read. Additionally, the slider borders must never be covered up from the slider being packed in too tightly. However, sliders that cross over themselves are fine as long as the borders are clearly visible.The last two sentences don't really have much of a point imo, there is no problem with the borders being covered up. It's always obvious which way the slider goes, and for short sliders it's generally impossible to make them big enough to satisfy this.
Suggestion: remove the last two sentences
