In this game there is a timer. To get the gold on a level you must beat a certain time. Normally you do that if you take the shortest path like in the first game, right? Yeah. But you'll still get a silver rank. How to fix this? You got to go fast. Holding down the shift key speeds up game world events but not the timer. This is the way to get the gold on a level for swiftness. Those easy sections or long stretches of nothing are perfect for holding down shift. Good luck!
