Still no new levels... Updated to version 2.4.7, but still on Space Cooler with nothing to do besides Iron Fortress and Alien Invasion events. Also, it's nigh on impossible to finish the Alien Invasion event without spending ludicrous amounts of money and gems each time. And for what? It's not being used to develop more content it seems. The game has stopped being fun now, even the special weekend events are dull.
