Amazing story. I loved it and had to go back to play through all the character's scenes. Cameos and references were really fun too. You really know your audience!
Eventing, pacing storytelling, all on point. A few of the transitions could be polished, like having animations cover characters that disappear, or making after battle transitions to other maps a bit smoother.
A few grammar fixes could help too, but nothing detracted from the overall experience. You captured the spirit of Harold!
