Funny enough, I am also planning to make some sort of animation showing off gameplay as the intro to make people stay on the deck ( deck gets less plays if people scroll over it in less than 10 seconds as referes to "unengaging" )
It will consist of showing few levels per time
"Swordsmachine" Fight
1-2 first arena (before the fire) fight
7-1 backup1 standing near one of the "mannequins" as if examining it
