First Buildings/ Sellable items

  • I am a bit unsure what buildings should I be aiming to build first, I have already built Recycling Plant but not sure what I should aim for next and then next after that. I have 2 concrete so was tempted with Oasis to help with energy levels but not sure because of the concrete shortage. Any advice would be welcome......


    Also I don’t know what to sell out of my warehouse or should I keep everything.
