There are some neat heuristics here you can use to guide your thinking, I found it to be a nice puzzle Found it pretty easy. It does have a nice design and a nice array of cuts. I would make more insightful reviews, but I don't want to spoil the solution. I got caught out, again, by going round a block instead of pushing it past where I needed to be. I think I was overthinking to start with and it took several goes to solve. Not massively difficult but not massively easy either.
