×...but -- unless I'm having a brain blockage and missing something totally obvious -- in order to do that I have to get the stalwart to first trigger the plate at (16, 5) and then, of course, manouever him to stand by below the top centre brain: all before I head into the bottom loop. For that to happen, I've got to get him from the light tiles to the dark ones (and back again) so that he doesn't trigger the door at (21, 27). And that's where I'm having trouble.

I understand that I need to get the top center brain with the stalwart without triggering the pressure plates that close the yellow door. The movement is very difficult for me. I could use some help with the path to take to first lower the door to the center brain and then to get around the little jig in the top center area.

This is quite hard to do.

Thanks
