Yeah! Got it in 32 tries. I literally "stumble" on solution when I realized that some blocks can be used differently. It did seem longer at first, but I tried it and it was not so much longer, so I kept working on that and within a few tries, I had the right path. I so much love levels for which the solution seems longer than the non-solution! :D
This castle is amazing. I had SERIOUS problems solving it. Over 20 tries, in a period of days. Was mostly two off, this way or that way. Really nice puzzle!
