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.
It's infuriating that there seem to be two 96s on the wrong side, but no 94 in sight. Regardless, on the correct side I somehow avoided the 2-off that others are referring to. I jumped straight from 98 to 94. Very nice level though.
Such a good level! One side brought me 2 off once optimized, so I knew it's on the other side and from there, it was a nice little puzzle to be solved. Very satisfying.
Since I was able to solve R2 on both sides, I now wonder if this one was also meant to be solved on both sides (I've so far solved it only on one side, in the set number of moves, which is currently 94, on the other side I can only do 96).
While I got 96 on both sides very quickly, and it also quickly became apparent which side had the trick, actually finding the optimization was very difficult. Fantastic level.
