So I just finished level 20, and it says it'll cost 5000 to travel to the desert. Fair enough. But is that a one time unlock, or will I have to pay 5000 every time I want to go back and forth? I want to play through the new zone and advance the story, but I haven't gotten 3 stars on every level in the jungle yet.
So you gotta let me know - should I stay, or should I go?
