Took me a while on a train ride to get this one, but it is quite difficult as the title promises. It’s still a nice solve with quite a few tricks packed into a small grid however. Thanks; here’s hoping for more down the line.
4 seconds over expert for me. Definitely felt like a Saturday puzzle, good logical flow.

Took me a while to solve and then I found I made some mistake. Got to say I was a bit happy to find that I need to do it again. Much pleasure! Thanks 🙂
