no end? But very enticing..
First off, saving.. awesome! I finished all the Missions. I liked them.
The income steps.. I like that the Cooler is basically your level. I even worked very hard to skip one!
I mined everything! Even the hidden row on the extreme right.
I'd make it end when there are no more resources to mine, possibly a high score for the most money when finished!
Last word: Really great game, great for strategy. Wish it ended. Good going! tew thumbs up \,,/_(^_^)_\,,/
