This was a very challenging game. For the first week and a half, I didn't play well and felt like I was falling behind my opponent. To top it off, I lost on turn 125 in the max-level red tower (I was 30 experience points short of becoming an Earth expert, but I decided I could manage without the oil). However, on turn 126, I managed to get 4 birds and ultimately make a comeback, outplaying my opponent in the late game.
Thanks for the game!
