The sound will probably be muted, I had a radio stream on while playing.
I Made a big mistake in getting the potion early and didn't have enough hearts to get the magical sword. Cost me about 2 minutes. I drank 2 potions in a row in level 7 on top of that. Wouldn't have survived without one though. Level 9 was kinda good with exceptions, the Ganon fight gave me a heartattack. :)
