This hexagon-themed level introduces the dual portal, which creates a duplicate of the player with the primary and secondary colors inverted, slopes, which can slide the player diagonally, and other decorations. It also formally introduces the normal-speed and the slow-speed portals, although they were originally released in Update 1.7 along with Electrodynamix. It is the only level to end in slow speed.
