You are in the very distant future at FopStra. The world has changed a lot, the latest technologies have appeared that allow you to quickly move through the air. Cities rose to many floors, the architecture was greatly simplified. In fashion minimalism, and not only in buildings, but also in transport, you will control the cube - this is an analogue of a taxi. At high speed, you rush between narrow buildings at narrow gaps and your task is not to crash into appearing objects that are in a hurry too. Be agile and agile, otherwise collisions cannot be avoided. Collect points for the distance traveled.
