Actually the way you see the guy jump and Angel Dash looked like how I was pulling it off. Like it didn't work on the first try. It takes a little mastering so I get why the guy struggled so much at the church.
Compaired to the other people I saw at the boot this guy is pretty average, if a little dislexic, maybe. He didn't do as badly as that, just on the plataforming(obviously...:/ ) and on the concept of knowing what weapon to use when.
