Oh believe me, I get it. It takes a bit of timing to get it right. But as long as you get the yellow or green, you're in good shape.
I'm used to using the arrow keys, TBH. "Back in the day" before Windows was a gleam in Bill Gates's eyes, I played a lot of old MS-DOS games; Doom, Duke Nukem 3D, Heretic, Hexen, Wolfenstein 3D, Rise of the Triad, just to name a few. You had to navigate by the arrow keys. So it's old hat to me. Sure, I ran into a few problems during the fight mini-game, even lost a fight on purpose during testing just to see what would happen. So I completely understand that it's not in everybody's taste.
