The manual resource collection aspect becomes automatic once you have a basic factory setup.

There's also a mod called long reach[1] which allows you to do most things without walking around. If you want to give the game a second chance I'd look into that.

To give an analogy with programming. The demo is more like setting up your programming project, which can be a bit tedious. While the normal game play is more like thinking about the software you're building, defining good abstractions, thinking about how to structure your code both on a macro and micro scale, keeping things DRY etc
