Looks really clunky and unfinished
But I just did some research and the ideas behind the game, specifically asymmetrical multiplayer, sound really promising.
Apparently, the "paver" creates a beam of energy in its wake. All the other "racers" try to race along this user-created track. The goal of the paver is to create a road so difficult that the racers fall off. The goal of the racers is to reach the paver. Sounds really cool.
