Ok, so I've been playing around a week or so. You've got me hooked.
A few things to consider (if they don't exist or have been discussed already):
1. Having a discussion area for the Flash game and another for the iOS version as there are differences. Some people do call out which version in their posts and it is very helpful! Specifically it would be nice to know the difference between the two versions since they do have a different structure (a FAQ of some sort perhaps). Not sure how easy it would be to make both versions identical, or if it is even worth doing.
2. Have a specific (and easily located) area for strategy, tactics and walkthroughs. This way things are hopefully easily found and easier to keep current. The video walkthroughs are nice, but a bit dated now. I certainly don't expect anyone to update them, those are a lot of work!
Thanks for the awesome game!
