Each construction is based on nodes, node can be wheel, wing, engine, balloon, propeller, tank etc.Nodes can be connected by edges, moved, rotated, added and removed.Vehicle can be divided to many segments by axes, axe can have rotation limit and can be individual steeringGame support air and water drag, wings can direct aerodynamic force to chosen direction. Nodes in water have own displacement, it can be changed in tank node so build submarine is possible
