This game has such a big potential, but it is not any playable at this moment. The pieces are very unbalanced. The artificial intelligence sucks. There are no new players. The developer should balance the pieces and keep it simple instead of adding more and more pieces.
I spend 3 days to get the medium achievement because of waiting times. Should I pay to get achievements easily? You can consider Kongregate premium membership too.
Thank you a lot! :D
