Thanks for the comment, yeah I didn't have time to make it more clear, I was planing a robot population mechanic (which you can also recycle) and energy but maybe it was to ambitious for 48 hrs, I will update it once the ratings are over. 

Thanks for the feedback, fortunately this is not the first isometric that I make, just the first tu publish, the math can be tricky at times.

Definitely an updated version is on the way.

Thanks for the feedback, yes it is indeed slow, I was planing on implementing population and energy with recyclo (ingame resource) has fuel, that permanently reduce your resource pool, and the turrets will be for defense against gigantic lifeforms that come time to time. I will defityl implement all of this.
