I get a little tired of all the Sokoban variants during things like the Thinky jam (Puzzlescript is basically designed for two kinds of game: sokoban, and everything else), but this was 100% the exception. When the challenge isn't "can you sokoban" but things like "can you avoid having to move any crates at all" or "can you set up the level yourself so that you can solve it", it's way more interesting. Thoroughly enjoyed this.
