If Dora stops running while on a path, just tap on the screen to make her jump and she will continue to run again.
When Dora jumps onto the ladder to cross over the gully in the Flowery Garden, she will move across as you tilt your device back and forth.
To collect the correct bears after riding the rainbow geyser in the Tallest Mountain path, be sure to tilt your device again so that Dora can grab as many as she can.
If you are still having trouble, please submit at ticket at nickjr.com/appsupport or email us at appsupport@nickjr.com.
