Order of worlds to be unlocked so it might get easier:

1. Unlock either Pirate Seas or Far Future first after getting world key

2. After finishing Pirate Seas/Far Future, go to Wild West

3. After Wild West, go to Dark Ages

4. After Dark Ages, go to Lost City/Frostbite Caves

5. After Lost City/Frostbite Caves, go to Big Wave Beach/Neon Mixtape Tour

There.
