We played with restarts; I took two games with 112, and on the third try, it went even worse. I was slowly losing goblins, and somehow, I managed to build a Castle after the birds and on day 6, sold everything I had for 0 to build behemoths. Desperately wanting to catch up, on day 7, with two birds and a behemoth, I went into the gnome lair with 15 units. Several morale boosts on a greased stack decided everything.
Thank you to my opponent for the game!
