That's ok <img src="/images/graemlins/smile.gif" alt="" /> I write those guides while I'm playing and then type them in later when I get time so sometimes I write them too quickly <img src="/images/graemlins/smile.gif" alt="" />
So you did all the first part, and you get the short little video and now are sort of ready to cross the bridge right? So you go to the shiny floor area, i.e. where you reset the pillars. You go to the reset pillar and take the sphere out, and push it down the ramp. You go down and reset the pillars again. Now you put your sphere into the far right to bring the icicles back, take the sphere from the middle and put it in by the ramp down. Now get the destructo sphere and put it in the lower level by the door.
Better?
