I had just enough money to place an angel on level 117. I almost lost and was about to surrender in the max-size map, but I managed to gather my thoughts and use a couple of advanced slow spells, along with a couple of archers dealing 60 damage, and with all the meat except for the angel Miriam, I was able to overcome the first and last difficult task. Then, on level 121, I immediately used oil on the checked max-size map. On level 122, an opponent appeared, but he didn't make it a few squares to the city.
In the final, the resources were comparable, but I had 15 cyclops and 9 angels against 35 ducks and 3 angels for Alkin, and there was nothing he could do against the oil.
