First the colonists should have a better way to go to their jobs why not add vehicles or something to do their travel faster and don't get tired by the travel.
A better way to product uranium, clay crystaline, obsidian etc because unlock transcendence is hard to get but It only unlocks few things and is transcendence we are super smarts right?
And the last idk what more but that was all I hope someone will read it and like it
I agree that colonist should be able to get to job easier later in game. Research a bus stop or something. A place where they have to spend money to buy a bike or something that we make to make there life easier.
