Very fun systematic solve. No step is too difficult but it was still very engaging for an “easy” puzzle, and not necessarily obvious where to look for that next step. Great job with the setting! It’s hard to strike that balance without it feeling mindless.

Advanced beginner here. It wasn't hard, but it was a bit time consuming as i had to slog my way through it cell by cell. So i gave it 1.5*
