There is a major bug on the battle mode. Not only did my dragon attack twice, but it attacked my own knights in the frontline. Needless to say I wasn't best pleased. A shame, because I did enjoy the game aside from that despite it getting a tad repetetive.
Once you get the hang of it with the British, it really becomes very dull very quickly. I also think the enemy AI needs tweaking, since they attack the first thing they come across, which makes it very frustrating if you try to be at all inventive with your defences, and rewards you for building the obvious fortress.
The developers of this game are ridiculously stingy. Not letting me build/upgrade more than one thing at a time without forcing me to buy gold (which I won't do) is absolutely ridiculous. Once I get the badges, I'm out of here.
