Wow, thanks so much for such detailed feedback. I'm really glad that you felt what we intended when you finished restoring the weather system. It's also really useful to know that you found it stressful. Balancing a game like this is difficult and we need all the feedback we can get.
Thanks for all your suggestions and bug feedback!
The conveyance ports do connect across different elevations, and the recycling boats can go up and down waterfalls. The googly eyes are actually intentional! We were trying to make the recycling robots look like Wall-E from the pixar movie. That's an interesting idea about tier 2 and the different biomes
Thanks again, glad you enjoyed it :D
