I'm at a loss with this game, not quite sure how the game even gets started! I've started a couple of faults to practice, after I've built a couple of rooms that's it, I've no food, power or water, no coins, no rewards, nothing. Each rush causes more damage, my explorer died, manage to have a baby though! I like the game but would be better to charge for the game and then play the game with plenty of coins and freedom to develop, rather than a free game but requires money to start, progress.
