Suggestions for improvement
1) When holding the mouse over a building - it could be helpful for new players to get an info-field about the building with the name of the building and what It can do. (then I don't have to open the building etc. to see what it can do).
2) After the battle match and other competitions, please send an e-mail with info about what you have won .. or not. This could be a functionality, which you can switch on and off.
3) Please make a video explaining the Hero sets and how to use them the best way. (could be a functionality which you can switch on/off in the settings).
4) Please explain when to use standard attack / and or enhanced attack against invaders somewhere.
5) It could be fun/nice if there was som kind of action-battles in this game .. with real-time Viking- battles including all weapons etc.
6) Please make it possible to move the buildings round in the town for re-arrange.
