I notice: If you load any game in any tab of browser ( Chrome for example ) and keep it loaded, then trying to load this game you see, that offline mode is kind a broken. It does not matter what type of game you load: Flash, Unity or others. If you want your progress to be calculated as offline, then you need to load this game in first place and only then load other games.
In some of the update fixes you write, that offline boss kills counts. Then why, when i goes to offline from this game at least 7 hours ago and farm 1 second to kill boss, i still not recieve achievements for boss kills ( 3600seconds/kills * 7hours = 25200kills ) : Boss exterminator and Boss murderer ?
Beating the opponent is too easy. For example, i send waves of viruses only in one line -> 2 waves an no enemy. Every line need its own health and not the all lines have one summary health. But in other ways is perfect for me, so 4/5
