For me it was all about strategy and clicking in the right places.
You have to follow the road when you click to move faster and just play the maps a few times. On my 3rd time run i got my time down to 7 minutes, it gets much easier when you learn the maps and where to click to keep going really fast!
Btw I absolutely love this game, it's just my time of game! ANGRY BUT IN A GOOD WAY!!!
