I like how the environment will affect the strategy should take, but maybe should have a forecast mechanism what the next effect will be and notify the player what the effects taking in place currently. I did rescued some civilians but the AI pathfinding didn't worked properly when there is a narrow door frame there in some buildings. And the sound cue regarding the random "spawning" civilians a bit weird too. It's nice that you made it as your entry, good luck on your game dev journey!
