I'm clearly missing something- Before I killed The Lights boss, I tried to collect the health square on the far right of Woshad, in the tree with the torches, but it's locked with purple chains. I tried going back after killing The Lights, same thing. Do I need a special purple key, or...?
I wasn't credited with the badge for completing story, either... "Submit high score" destroys all evidence of completing the game, i went back and tried to beat final boss and the arrow keys couldn't register. This game isn't worth your time.
