Completing levels is a fundamental way to unlock new content. As you progress through the game, you'll often unlock new levels, characters, or items.
Critics of the "everything unlocked" approach might call it boring. "Where is the tension?" they ask. And they are right. There is no tension. There is no fear of falling. There is no "one more try" frustration.
The game defaults to a "debug" state where Wishes are unlimited and Crystals are uncapped. You still have to manually tap to buy the unicorns, but you can do it all in ten minutes. Once you reconnect, the server may reset your progress, but if you save the offline data, you effectively have an everything unlocked full save file.
