Ok I took my time to make a more educated comment. Retreating shouldn't cost diamonds, maybe gold to the enemy at most. And talking shouldn't be charged for, i mean sure we get 10 a day but have you actually made sales off people needing to talk so badly they'll pay for it? communication is a main part of a multiplayer game. Another thing is from signal flares to damage boosts all the way up to automatic researching and construction people who pay against people who don't, people who don't wouldn't stand a chance. My point is a good amount of simple things cost diamonds, its a little too much sometimes the point is if anyone wanted to spend money on it they would get a clear advantage in any combat situation by a long shot and that seems unfair to casual players. This is just my opinion on the situation.
Base of the game I like it but its slow and the same thing over and over. With some improvements it could be pretty good. Also i saw a comment saying "This game has too many bugs" Is that supposed to be a pun? Because I like it.
Final boss is just about pure luck, with all upgrades and 10 fights iv hardly gotten him to half hp, Should consider an update with all the similar problems. The boss hits twice as hard as hard as you and takes half the damage while having double hp, (3x if you could the first part.)
I liked the first one this new one is amazing though, Only thing is there should be some sort of penalty to people just stalling to get booted as it costs us a win and saves them a lost.
