This is my second run after a long time. I managed to get my world record back by planning my run much deeper in the game and trying to use a different hero. Overall, it was a successful run, with the exception that I forgot to equip the Lighting Bolt when I unlocked the Black Knight, as both unlock at the same time. The first levels are the most difficult as with only your starting units you will have to deal with one of the following units: -Black Knight (Easiest) -2 Centaur Archers -Black Knight + 2 Centaurs -Black Knight + 2 Centaurs (spawning about 2:40) -Witch (spawning about 1:40) This run took me 164 attempts and a few hours of research on how the game works.
