Great game, maybe a bit easy though 'grand big battle' was over in 2 hits.
Only glitch I experienced was when you already click te continue after a battle, and before all the screens stopped moving... then the game hung, but if you wait till they stop moving: no problem at all.
I agree that either there is a bug in winning new cards, or that we just don't know the prerequisites for unlocking a new one... Anyhow, it's not as hard as some of you claim... just don't keep sending everything at once...
Nice game, but the graphics sometimes spoil it for me... water going behind the pipes without any problem, but then pipes cannot go behind other pipes... stuff like that.
Strangely enough the Queen stopped leaving her colony after a while... and she didn't even defend it. So it was really easy taking it over...
I don't know if this was a feature after her taking over x-number of colonies or just a bug (I know... what a pun)
I like the game, but I have to agree with some of the other comments. Just magically granting the enemy a ton of ship, subs and planes when they're under attack isn't very 'challenging'.
If they had all those in reserve, they should've just sent them out at the beginning, and ended the silly war :)
