Having played this level when I was starting out, and coming back to this level after over two months, I can really feel my growth as a player.
I used to be stuck 2-off on both sides, but now I was able to figure out which was looser and quickly find the solution.
It's a nice construction, it makes great use of joining the separate sides together in a single level, and I don't think either side would work as well if they were separate levels.
