I really enjoyed the break in! I can't solve many 2/5 stars so I'd definitely give it a 1/5.

Very nice approachable puzzle (I got stuck in the middle due to my own ignorance). Beautiful interactions between clue types.

I found the break in really challenging, but I think I was missing something obvious. Once I got the break in everything elder was very quick.

I rated this 2/5 difficulty

This was a great approachable FoW puzzle! There were a lot of nice ideas, and the solve 'flowed' very well.

I think this puzzle is overall a low 2/5 difficulty, as it did take me a while to spot a one of the 'key steps' in the early midgame (and this step seemed a bit too difficult for a 'true 1/5 difficulty puzzle').

That said, none of the steps were 'complex' (difficult) conceptually/logically, though a few were tricky to spot. A beginner solver should be able to solve this puzzle independently if they are familiar with the 'basics' of each rule[set]. In any case, I definitely recommend solving the puzzle for an enjoyable & approachable solve!
