Your personal shield generator recharges on its own, and you can pour
that charge straight into a machine to kick-start it. Help your colony gather
resources, get a burner running, and build out a power grid — and the machines
gradually stop needing you standing next to them at all.
Then you stop doing it yourself. An Assembler. A burner that runs
without you standing on it. A Robot Fabricator that prints machines with names, jobs
and skill levels of their own. Every machine you raise is another thing you no longer
have to hold a button for, and the game keeps handing you bigger levers.
Every upgrade is a rung. Your own shield charge to a biomass burner
to solar to stored energy. Hand tools to power tools. One robot to a shift of them. The
progression is deliberately incremental: each rung exists because the one before it
ran out, and you can feel exactly which bottleneck you are buying your way past.
And it ends in the space age. That is what the title describes and it
is meant literally — the climb runs from the first rock you break to a starship.
The rungs between are the game.
