Playing style

[soapsoup]

Hey, so i'm still kinda new to the game and id like to know if this playstyle i use is optimal, i play two handed, i use the arrow keys,i use my left index finger for up and down, left middle finger for left and right index finger for right, this generally works for very difficult, but when it gets to challenging or above i just can't keep up with the bunch of arrows that appear, i'd like to know if there is a playstyle that can help me get better at these difficulties, or if just need to get gud.
