Nano wars did it so much better because it actually took strategy but this game butchered the entire game by not having any troops in neutral zones so now its all about sending troops to each zone as fast as possible
A huge step back for the series unfortunately the game is entirely boring now and all you can do is click to send vaccines not to mention there is no way to change the speed which makes the game incredibly boring.
massive glitch : multiple clicks on 'next day' will indeed skip many levels thats probably why you didn't beat the game in 11 days only buying artillery
