Worlds and World Keys
Hello.
My mother is playing this game but she doesn't speak english so here I'm instead of her.
She's got a small problem.
She already unlocked alot of worlds and played it for few months already. But she told me that "She had 9 world keys and suddenly it jumped to 12. What did I do to get them?"
Also she doesn't know what she can do with these keys. Like how to unlock new worlds or how to spend them?
Thank you for replies.
