I was playing the inkvil fortress level and open all the boxes then died when the dragons started flying about. When I went to replay the level again the rainbow box no matter what will not unlock now. Is this a glitch? Why won't it open?
The rainbow box is opened with a sword. Did that not work either?
Try with sword man! 😂 😂 😂 😂 😂
Also once you find all the puzzle pieces, crystal hearts and color buddies you get a master key (among other things)
