Stmubled upon this on the puzzlescript library (the itchio version has more levels than the puzzle script though, I saw a screenshot and didn't remembered that level)
Tried because I also did a sokoban with leaves but it was more lika a good snowman is hard to build (https://koliao.itch.io/ot)
Really struggled to find out how to twist (it was by accident) but also it was satisfactory to learn
I enjoyed it a lot :D
