Ok, I finally understood that you're supposed to balance 2 worlds at once but can check what you did in the other one only once every 3 turns. It's interesting, but I feel like the presentation is uselessly confusing about it. Good idea anyway.
Thanks for taking the time to try it :) We clearly see now that it is quite hard to understand. Do you have any feedback about what could be improved in the presentation?
I'm not sure. What I meant is that the game don't let me easily switch between world to observe or experiment to understand what's going on (if I experiment too much I lose quite quickly). Maybe all buildings should be available from the start ?
