Passengers will have a dot on them until their requirements are met, this is the best way to know if a level is solved or not

World 1 - A Day at the Park
World 2 - Up and Down
world 3 - The Desert

Unlocked after completing each world, but may be delayed or not unlock when expected.
If this is the case, try the following:
- Wait 1 minute
- Return to Main Menu
- Return to specific World
- Open level 1 and press next in the top right until "Next World" is visible.

Certain levels do not use all pre-placed tracks, and certain levels have placeable tracks left over.
A track may look buggy, but if all requirements are met it will succeed.
Be sure to read the requirements of each passenger to make it easier to follow along with the guide.

(Level 6 is after 8 instead of 5 in game)
