Thanks for the feedback !
You're absolutely right, we didn't spend the much needed time on the bar you mentioned. It really should give the effect of progression to the player since it's the only visual cue for the ongoing war.
Our first thought was to place arrow heads in a certain direction, which would help the player to understand who's winning, so that he/she can come up with a counter strategy.
It's certain that we need to do a lot of bug fixing and polishing. Thanks again
