Plan A is one of the Tunnel options after completing the Way Back. It consists of sixteen levels, with the last one, part 16, being one of the hardest levels in the game. The only tunnel that connects to Plan A is Launch Site A, which branches off from Plan A, part 8.
The following is a brief description of the story in Plan A. More information on the story can be found here.
After beating Plan A, part 8, a cutscene featuring the Duplicator and the Child will begin. The Duplicator had just finished explaining to his son why they don't use violence to solve their problems. All of a sudden, the Duplicator turns around and realizes that the Child has his balloon back.
After beating Plan A, part 16, the Child says, "I can't wait to be home again! Dad, are we almost there?" The Duplicator has a couple of nostalgia moments and then the Child daydreams about what they will do when they get home.
After beating The Way Back, part 16, the Pastafarian is teaching the Child the Condiments of Piracy. The Child is very bored and falls asleep. The Duplicator arrives and the Child wakes up and hugs him. The Pastafarian leaves. The Duplicator asks his son if he learned anything and he replies with, "All I learned is that pirates are super boring."
|Not too easy|
Note: After completing Plan C, part 8, the Pastafarian leaves the group, so she is not a playable character from Plan A, part 9 and onward. The same goes for Plan C, part 9, and all the levels chronologically after that event.
