It's not bad but quite slow. Also, in the first town I sold my villages for an upgrade and now it seems I have to start from zero again for the next town. This is where I stopped.
You did nothing wrong. But you don't start from scratch. The town's bonus to villages is resource income, which provides a big boost to initial play. Check it out in the preview (hover on the values) and increase it before starting the village if it's not to your liking. If it's going slow, let it idle a bit and spend the surplus all at once, there are no resource caps, only requirements. Thanks for playing!
