This game suffers from two massive flaws that render it almost unplayable. 1) it allows you to undo your turn even after you have completed it 2) you can not swap leaders. This means you can backtrack after a conflict is finished, which ruins the game. Not having the ability to swap leaders removes an important strategy from our disposal.
The game can be great, but it needs a lot of polish. The art is terrible. The developer seems to have abandoned it.
