MAIN STEP

The main thing you need to do is when the stage starts turn the character around and start walking towards the screen (you) until you hit a invisible wall. Then you start to run towards the road and you will see your score start to go up. Once you get close to the road turn around again and run back towards the invisible wall and then rinse and repeat. You will see that your score will still increase with out ever stepping foot on any road (basically avoiding all danger). The only thing you need to avoid is the sewer holes.

The reason you want to do it this way is that to get all the achievements you will need to reach a high score of 5000 in one life (which is NOT hard at all if you play the game regular....nut for those who want to get the achievements quickly this will be your best bet)

You repeat this step 5 or 6 times you will get all the achievements in like 3 minutes.
