Amazing little gem of a game. To be honest, I am not a huge fan of chess. This game fixes that similar to how chess 2 fixes the issues for chess with me. Because you have different armies, you play more towards the board state then trying to outsmart your opponent and thinking ahead 14 million turns.

In terms of balance things seem fine from what I have played. Even powerful combinations are situational so I think you have done a good job so far! :)
