Why the objective is a letter, not a base
A moving letter gives every tactical choice a destination, a deadline, and a person who is waiting.

Many short strategy games ask you to protect a base because a base is mechanically convenient. It sits still, gives enemies a destination, and creates a clear failure condition. But it rarely tells you why this particular battle matters.
Last Light Post starts with a different question: what if the objective were already trying to go somewhere?
A destination changes the shape of defense
The letter moves toward a real mailbox. That means progress is visible, danger has direction, and route choices affect more than a timer. A courier who shields the envelope, repairs the road, or speeds the delivery is doing recognizable postal work—not using an unrelated combat class with a postal name.
The current prototype keeps the battlefield deliberately narrow: one route, one envelope, and the most urgent threat in view. The goal is for a new player to understand the job before they understand every number.
The ending belongs to a person
Winning is not only the removal of the final enemy. The run completes when the recipient can open the letter. That short reading gives the choices before it a human destination and gives the player a clean emotional ending before the next delivery begins.
This remains a design hypothesis. The project has not yet proved that players will value the letter more than a familiar stationary objective. That is exactly what the prototype is built to test.
