I am trying to get the the 2nd level on the Challenge of Hades. I have killed all of the enemies on the first level. When I go up to ledge on the left side and go up and then I go outside, I have to open a door. I go down the hall, then I come to an area where the floor moves, I can get past the first set but the second set I can't get over. Can anyone help me here. I have tried everything, I am stuck at this point.
