Easy Hard Stages:
In the hard stages where you have to tap faster you can tap the screen with multiple fingers on one hand on each side. This will enable you to tap at half the speed that you normally would have to which makes it very easy to beat even the hard stages with three star scores.
You can extend your slide and swipe indefinitely by repeatedly swiping left, right or down. Doing this makes you stay in the left, right or slide position which makes it easy for you to avoid or slide under obstacles.
Don't worry about the timer as your only objective is to not get hit by anything while you are running after Archie.
