A miniature robot was sent to the inside of a large installation in order to arrange its work. He knows a lot and not only repair broken nodes, but also create new ones. But first, he needs to get to the right point where there is a problem that needs to be solved. The robot does not know how to fly, but it can create multi-colored neon platforms under itself in the form of a tower and thus rise to any height. You must stop the newly appeared platform in time so that it becomes exactly above the previous one. A shift to the right or left will be cut off and the new platform will become shorter in Neon Stack.
