XStep

xStep is the tenth level on Geometry Dash. It is the first stage marked with the Insane difficulty as of Update 1.9.

Description
xStep introduces blue pads and blue rings/circles on the regular path. The icon assumes three different forms through the level— the cube, rocket, and gravity ball. It is similar to Cycles in difficulty and features multiple tight rocket scenes. xStep is also the level that uses the greatest number of blue pads out of any level in the game, present throughout almost the entire second ship scene. The level also introduces full checker bricks and another block (previously seen in Invincible Stage while getting the second coin in Jumper).The level also introduces wavy platforms along with the wavy thorns.
