"If you see somebody at low health, you need to be like an Execute Machine.
You know like you're looking for people...
20%? You see somebody at 20%? BOOM Execute.
See somebody at 20%? BOOOOM Execute Execute Execute Execute."

What is this?
Back in 2015, Asmongold (videogame streamer) made a guide on how to play the Warrior class in World of Warcraft. It boiled down to spamming the "Execute" ability whenever you can. Asmongold explained this while swinging his hands in the air as a demonstration.
That 10 seconds clip of him attacking the air inspired me to make a game following Asmongold's words and motions.
