Testing something.

Map that have sliders considerably slower than normal. The slider must last longer than four beats and the ball must be noticeably slower on it or any like it compared to the normal speed of every other slider in the map. Usually seen as a gotcha at the end of maps to trip up people used to playing at a certain speed beforehand.

Maps that have incredibly long-lasting sliders, either because they're just covering the entire screen or are put into a special shape. Should last for at least 16+ ticks, assuming a standard 4/4 timing. (eg. The final slider of Raise my Sword)

Any maps with buzz sliders. (eg. the sliders in the middle of The Big Black) 1* maps may have sliders with only a minimum of 4 reversals without the closeness of the ends. 3*+ maps must either have sliders with reversals lasting longer than 2 beats, or buzz sliders with more than 5 combo.

Maps with sliders of a relatively moderate to high velocity. Should be doable by players able to comfortably play 3-4* maps, but still tricky/difficult.
