1 star for me. Nothing really difficult other than standard cages combinations.

Very nice, but since I could solve it, clearly not more than 2*.

This is the setter and I am new at this. I'm clearly having issues classifying the difficulty of the puzzles I'm submitting. Can anyone tell me about their break-in?

Went through without a hickup. Two stars is justified.

Lowered the difficulty one point based on feedback.

Too easy as 4*. Maybe 1 to 2* is more suitable.
