The build
An idle builder about a foundry that has already failed. You are not growing a factory so much as taking one apart and feeding the parts into something greener, and the numbers go up either way.
The simulation runs on a fixed tick that resolves the same way whether the app is open or closed, so a week away produces exactly the state it would have produced had you watched it. No fake offline earnings, no timer to pay past.
Our most argued-about release. The economy shipped 30% too generous, we corrected it eleven days in, and the review score took a two-week hit before recovering. We left both versions documented in the patch notes because the players who noticed deserved the explanation.
