Temple run 2 progress scores are lost

Go to settings --> App manager ---> temple run 2 and than (Clear data)

Temple run 2 is currently unavailable for Nintendo DS systems, but it is rumored that it may be made available sometime in this summer.

If you save in a temple and quit, it will always take you back to the beginning of the temple. Even so, you keep your progress through the temple like rooms visited, chests opened, and keys found.

I think this is the same problem my son had. Do the enemies just keep coming?
Here's the solution.
After building up enough combos you get a lightning bolt in a yellow circle on the screen. Press down the top of both the analog sticks and before the countdown runs out do a superbark (L2) while facing the far wall. the wall collapses and you can progress!
