Please could this be fed back to the game team @QueenB :
In recent weeks some players, including myself, have been placed in a test group in which all episodes are muddled up, meaning that the levels are placed in a different order within each episode. This apparently seems to test player reaction if the hardest levels are clustered at the end of the episodes. The problem with this is that players are lost if they hit a particularly hard level because the YouTube videos are different so the option to watch those for help is not available to these players. This is terrible!
Also when they post here about their levels we cannot help them because our levels are different. The only reason I can answer some of these questions is because I happen to be in the same test group.
