I only upgraded Grand units on the third week.
On day 117, Solmyr kills 19 snipers, and I run towards the central village. Everywhere, there were terrible stacks and a lack of resources; it was a really tough situation...
On the second week, from the opposite side of the teleport to the center, I see, oh, I cut off 2 units and with Solmyr, I push Marusia back, and I start to gain ground. I take the computer's outpost, and on the third week, I take its Castle. I start building up my army, gathering Hive units, and I take a Utopia - a level 2 unit with Chain Lightning and Boots of Levitation. Kirill has Earth...
In general, the opponent ran around without Castles until he was defeated. At that point, I already had 2 Inferno Castles, a dwelling for Ifrits, Armageddon units in the Tower, Scroll, and Box, and a Demon unit...
Thanks for the game!
