I thought this was a pretty nice map; good reuse of elements and there were some unusual design features to the puzzle. The large number of elements add to the difficulty somewhat. I did get trapped once and had to revert to an earlier save. I stupidly managed to get myself into the box that has the portable wall for the light bridge that is always on. I'm not sure why the grate isn't flush against the wall, unless you were trying to avoid the cube-thru-grate exploit. Very enjoyable map.
Thanks. Unintended solutions are my weakest points in puzzles.
