After playing a few of the smaller, recent sokoban inspired levels, I learned these structures commonly make use of a structural rotation of several blocks in order to get them in a particular “perfect” position. Once I finally escaped with all 5 blocks alive, the 593 came pretty quickly.
Tried for a bit to find some more. The ending had a lot of different structures/builds. Most things seem to come out the same however.
Ah this resolved my feeling that the late game was messy. Good find Meow!
