Development guide · Updated 24 October 2026 · Systems are planned and subject to playtesting.
Rain, cold and wind are planned to change route decisions and delivery difficulty. Phase 1 uses simulated conditions, with no paid weather API required.
A season is not a forecast
Calendar-based seasons and climate patterns create believable scenarios. They do not tell you the actual weather outside. Future live snapshots would have a source and timestamp.
Make the trade-off visible
A harder shift may offer a bigger in-game reward. The route lab uses illustrative values so you can experiment with this idea today.

The browser route lab is a small strategy prototype with illustrative numbers and fictional streets. It is separate from the mobile game.
