Stuck in tomb of miktrull walls not moving

I know this is 3 years late, I just got the game, but as far as getting the last and hardest chest in the tomb of miktrull, this fella’s answer is correct. I dunno why those walls won’t move now, I can only assume I did that area during my first run through of the game. Maybe that area isn’t accessible again? I’m not even sure there was a chest in there. I’m gonna play with it again and see if there’s a switch that activates those walls, but I was at least able to get that chest, which was the last one I needed in the game. Hopefully that helps some of you! Thanks jBuck383! 😉
