A fairly large and confusing search space, even though the level is just 10 by 10. Hard 18/43. This was impenetrable to me in PP2; all the hi19 Patho levels really helped. Initially 2 off, then I came back and got it, neat level. Five stars for defeating me, my inability at pipelining strikes again. Loved that one. One star less for the fact that there is work only on one side.
