in this case the took piece was too powerful being able to move all the way across the board so I limited it to 3 squares. Hence it is cheaper than the bishop piece since it can still move it's full range.
I had considered different abilities for each side but I thought it was more balanced to keep them the same, and it fit with the theme since they both used the same tactics in the Cold War. However, if you look close the proxy war piece is an m16 for capitalism and an ak47 for Communism.
Overall though you have some good points and 7 days was not enough to properly balance a game like this. There is definitely opportunity for different game modes in the future where maybe each side has unique powers.
Thanks for playing and thanks for the feedback, I hope you enjoyed 🙂
