Thanks for your feedback!
I liked the idea of making a very heavy fog of war based game for the theme Darkness, having more pressure to find where you are being attacked!
For the resource system, I wanted to have some situations where you wanted to stock resources to avoid your production buildings being full (thus losing exceeding resources created), but I ran out of time :') So I agree that it would have been better to pick them automatically with the current state of the game.
