Shortcut in Metal City at night
At the beginning of the race, go as fast as possible. Then, get the highest jump possible without going any slower. Also you can do one trick but it is easy to make a mistake; do not attempt it unless you are skilled at angles. If done correctly, you will have jumped on a platform that leads through a small part of the stage. The Power attribute is best here, because there are many obstacles unless you are skilled at dodging.
