Wow! Thanks for taking the time for making a so extensive review!
The 4th ending (The Brighter Future Outcome) is the most difficult one to get (although many would argue that the result is not what one would call "a bright future" :P) . To get it, you must find the perfect balance between industrialisation and nature, while keeping the population well fed. It's not an easy task because the tile deck gives you little margin for error. One of the improvements I have in mind is to give the player some tips on the polluted and starvation outcome, in order to help them to get to the other two more difficult ones.
You can move the Camera, but I totally forgot to mention it in the description or to add something in the game so the people would know!!! To do this you can use the ARROW KEYS (At least I'm going to add it to the description, thanks for pointing this out).
I'm glad that the fact that the game is too short was the thing you didn't like. It gives me hope that the game could be expanded into something more. The proximity effect that you mention came to mind at some point in the development, but I wanted to keep it simple for this prototype (But it would surely improve the game).
I'm really glad that you enjoyed it!
