Finished the 4th Quest. Red Ring was a terror to find, but got it and slammed into Ganon, thanks to the YouTube playthrough.
Screen 16, get stuck if you don't have the ladder and try to walk through. It's too easy not to find the Ladder.
Bubble rooms are severely broken. The enemies constantly take out the Bubbles, if they're permanent you could get sword stuck. Please check it.
