HI !

First, all apologize for my bad english langage !

I see that sometime it's not possible to take back our move (expect quit the game and rejoin), why don't add a cancell key, a way for someone to cancel the last move he did but he don't like during his turn.

I also appreciate if when I play with alliance, a teammate can stack unit on my city (with mine) to protect the city against the other player.

I hope you can understand my mind !

If you're playing in a browser you can hit refresh and that will undo all your moves
