Fun and fairly easy, to be honest. I encountered neither a tough break-in nor a tough step mid-solve. Rather, the break-in seemed kind of obvious, and maybe it helped my middle game that I did a bit of colouring.

Great puzzle. Especially the break in. One step near the end was 3* with logic only to me. Many very clever steps. Great setting thx.
**
Thank you for your comment, wuc! It is good to hear you liked the break-in. I think I might know which tougher point you are refering to. That could be the hardest deduction in the puzzle, but overall it should be easier than 3 stars.
