seems I made the mistake to set up two of each terra forming device. I got the drill and the rafinery way before the autofeeder that I am now unable to get because the game ends before this. And I can not load it and and stop all devices before the game ends again :-(
It's not a mistake, it's actually the correct way to play it, but notice that the DEMO progress bar above is based on terraforming. Full game will of course be completely open, you would be able to do whatever you like. For the demo, If you want you can always start a new game, it should be easy to copy the scripts you already made so that you can see the remaining demo features.
