So great to see you back here and to hear you’ve still been at it! This puzzle is a great reintroduction. I don’t keep up with emails discords or websites well so I’ve missed yall and the puzzles!

Nice puzzle with standard constraints. Don't do like me, I kept forgetting the second little killer on te negative diagonal and solving was becoming a nightmare :p

Actually solved this slightly faster than my average 1* puzzle time.

That was fun! The small little killers led me into a bit of a false sense of confidence about how easy this puzzle would be. Still pretty approachable, but not quite as easy as I'd initially thought.
Kinda weird I don't remember this one; I usually keep up with your puzzles on Missing Deck.

2* if you go in blind, perhaps 1* if you read the title first.
