First of all, congrats on the submission...
What a great concept!
Straightforward gameplay that creates so many possibilities and strategies.
I ended up with grey level most of the time but that is because I was zooming through the options lol and most of the time it felt like just adding the green energy was the right thing to do. I can see a dedicated RTS player spending a hefty amount of time to understand and play the game!
Sweet art style...
The Politician seemed overall better choice as compared to Engineer or Scientist so I would assume the game needs further balance because there's plethora of strats,... regardless the game has a good stage or a starting point for the same.
I believe you would have gotten this suggestion before, but just in case, would love an option to remove tiles, as in the beginning I had many tiles placed accidently while learning the game (unless that is intentional in game design - like most of the policy decisions taken in real world can't be reversed easily). I seemed to always have been low on Production to upgrade so it was almost always greyed out for me.
Made in Godot! Great job on that... I am definitely one of those who do see the power of this engine regardless of all the workarounds you have to pull for being an open source though don't always prefer it XD.
P.S.: My high score was 6000 in about 4 playthroughs, curious what is the best score one can get.
