Trees on the hill. A saw. A truck at the yard. That is the whole factory.
You hire a lumberjack. Logs start piling up. But there is only one sawmill,
so the log yard fills, and the lumberjack stands there with nothing to do.
That is the game. Not "buy the biggest upgrade" — **find where the line is jammed.**
Hire a second lumberjack and nothing changes: the sawmill is still the bottleneck.
Hire a fifth and the forest itself runs dry, because saplings do not grow that fast.
Every number you raise pushes the jam somewhere else. Reading where it went is the whole job.
Later the line branches. Bark becomes charcoal, sawdust becomes paper,
planks become veneer, glulam, chairs, desks, dressers. They all fight over the same planks,
so where you send them is a decision.
Then the timber stops being something you only sell.
A town rises to the east — houses pay tax, shops trade, and the villagers say what they see.
North of that, a resort: a ferris wheel turning, a cinema, an aquarium.
And north of the forest, black shafts open in the gravel. Adventurers go down,
and they need gear — planks, veneer, glulam — every single run.
Sell it, build with it, or arm someone with it. That is the choice the mill keeps handing you.
The factory keeps running while the app is closed. But if you left it jammed,
you come back to a jam — and the report tells you exactly what was stuck.
・Twelve stations, eleven goods, one line you can see from end to end
・Nothing is capped. Levels, speeds, yards — spend as long as the money holds
・A hundred quest stages, from the edge of the village to an island in the sky
・Adventurers wear out and are lost. Treasures stay
・Free. One banner ad. No forced videos, no timers, no energy
