Celtic Cross by Patrick Junke

Rules :

Place the digits 1 to 5 exactly once in each row, column, and outlined region.

Digits in dotted-line "cages" must sum to the indicated total.

The central region is covered in fog — its clues are hidden. Placing a valid digit in any cell clears fog from that cell and adjacent ones, if present.

Definitely not a snack, and definitely 2*

Patrick> Thank you ! There are very smart people there, but I found 1* was too low rating also for this puzzle ; everyone has to find his own break to this one, so I would not give it to a beginner.

Nice puzzle! I think the difficulty is fair. Could see an argument for 1* but 2* is fine as well. :)

Patrick> Thank you Zibl ! It's nice to have a comment.

Don't hesitate to tell me if you think I have to change the estimate difficulty.
(I personnaly founded it difficult at first, but setting it, knowing it better and better, I founded a path that takes me now 3 min to execute.)
