The start was generous, so even with a 5k rollback I put the birds in the fort on day 1 (the campfire helped with 6 mercury, otherwise there wouldn't have been enough). Only left the respawn on 117, and found an external dwelling of birds in the adjacent zone. Took 3 cons 1+2+1, then this external dwelling of birds; got Town Portal on the second try, and an imp on the first. I saw the opponent's maneuvers, and on 131 managed to cut off his main army and lock him in a treasure zone. Rebuilt Dimension Door on the 4th try, took the double Dragon Utopia with wings. Wanted to go into the super-treasure zone, but the opponent surrendered. Thanks for the game.
