I LOVE it. It's like TABS but with narration. The simple artstyle also works very well. The rivalry between the two grandpas and their names remind me of the two old men in TF2 lore, and i love the stupidity of it.
Really the concept is so simple but smart, the back and forth ensure interesting battle while keeping it balanced. I even got surprises with unexpected results sometimes. I got the West to win 5 or 6 battles one after another!
Really creative units too, and great animations! Would love to see more units added
It gave me so many ideas of things to code and mix with procedural generation :)
