OH
I kind of ignored that character a bit because the balls seemed a bit pricey and by the time I came back to check on them I already had the ability to fly. I also thought the chest was put there as a joke because the one solution I could think of (kicking with the heavy boots) did nothing. The ending is great thanks
(there is a bug with the ending though where when I went back into the world right after the credits, I couldn't open the bag or the pause menu. not sure why. Alt-F4 fixes it thou)
