It added the mirror Geometry Dash portal in version 1.1 of the game. Bypassing the mirror portal would cause your screen to flip. If you were heading straight ahead, the level would reverse itself. Due to this, playing backwards is made a little more challenging. This gateway might be used by creators to increase the difficulty of their level. The community has a strong aversion to mirror portals due to the fact that players find them bothersome to navigate. Another tier has been added with this release. Here in "Time Machine" you'll see the mirror portal trick used repeatedly. The update concluded with the addition of two new icons for character customization.
