I'm looking to start learning all time pieces but my biggest concern as a noob is using keyboard and mouse. I especially noticed this after going back to do some of the bosses that running to the left while sprinting and trying to dive is the most uncomfortable thing in the world. Should I find a different key to bind dive to in order to make it significantly easier or is that specific form of movement rather niche? I do have access to a gamecube controller with adapter so I could potentially use that if keyboard isn't ideal

Its personal preference but I personally use keyboard and so do a few others, Gamecube ive heard can hurt the finger aster a while of playing but ive never used one for hat myself, I'd say best bet is to find whatever youre most comfortable with in most situations and stick with that

if you only want to change a few buttons you can edit a file in the game files, you should ask around in our discord for information on how to rebind using game files. people are more active there than on the forums here
