The flashing thing is a helpful tip. I was going to suggest some sort of visual beat timer ( Ala Crypt of the Necrodancer )
Mainly because I'm deaf, so it's difficult for me to " get into the groove" once I lose my place ( the reason I figured out I was taking damage on seemingly nothing )
I can play COTN, ( albeit; not the best) So i figured this was something i could mess with as well.
I'll look for that flashing, that would help immensely.
I already watched your youtube video to see it in action, as well ^^b
Thanks for the reply!
