I can access Backwoods forest but it shows all of the challenges as ‘locked’. Do I need to finish Twisted Canyon in Kithgard Dungeon to unlock levels in the forest? If so, how many more levels in the dungeon will I have to complete?
Once you completed Kithgard Gates, you will be able to play the Forest levels.
some of the levels are locked because they are premium levels
you need to buy premium to access to this levels.
