I don't remember exactly where it was, but I do remember there were a lot of blue blocks, like a solid chunk of just blue blocks. I cleared too many of them out of the way, so I tried resetting the level, got stuck in a solid wall, and there were red blocks behind me, so when I tried to perspective shift out of it, I would just die. That's as well as I can remember it, so hopefully it helps a little? haha
