Geometry Dash Stereo Madness X is a Hard level rated 4 stars created by the user SpacePark. This level is in version 1.3.
The level starts with jumping, then climbs up the poles, jumps on the half-block platforms, and jumps on the half-block spikes. Then the background changes, and the cube has to jump on the pillars without touching the spikes located on top of them. If the background changes again, you get trampolines. You should jump around the spheres and poles again, and then the background will darken.
So the cube becomes a ship. You can touch the floor and the ceiling, but not all the time. After that, the screen drops down and the same part leaves, but with a UFO.
The screen redisplays. The UFO turns into a cube, descends half a block, and jumps over a few spikes. Then you just have to jump over the poles and platforms in time. Then the cube goes on a ship. You must fly through a tunnel dotted with thorns. After doing that, the level is over.
