Ok. Sherlock Holmes once said something like "Once you have
eliminated the impossible, whatever is left must be the answer, no
matter how improbable it may seem".
So, you can't get a block on B8 or the water next to any of the
guarded windows so you must enter via L8. The only other things you
can move from outside are the 4 mirrors and an AT. Two of the mirrors
are stuck on the LH wall and you would have moved one of them to A8
in order to push K8->L8.
What about if you push one of the free mirrors to J8? Don't waste the
AT because you will need it to stand in for one of those mirrors
which you will be forced to sink.
You should be right now. Good luck.
