I kept changing my sleep schedule, had headaches, and played like a complete idiot. For a third of the turns, my heroes would sometimes run back... after saving, things got even worse – I completely ruined the army of the second front, losing half of it and dismissing the other half. For two weeks straight, I kept forgetting to deploy angels. It was especially frustrating to lose all the time in a max-concentration battle with Mephala and her main army, and not be able to attack with my main hero ((( – that day allowed Kyrie to take the key Utopia with Castle and Fortress under my nose.
Towards the end, I attacked Craig near the Castle (20 archers, 20 harpies, 9 wonders, 20 phoenixes) – I could have combined my forces and made 30 archers + 70 harpies, 1300 skeletons, but I decided to be a hero, and with a two-fold advantage, I lost the battle. I thought the skeletons with 7 speed would control the field, but checking in the physics engine – that's for losers.
