Lanternward

Place lanterns in the night streets of Veldrenmar until every alley is lit. Lanternward is a logic puzzle in the classic Akari ("Light Up") family: a lantern lights its whole row and column until a rooftop stops it, numbered roofs say how many lanterns stand beside them, and no lantern may shine on another. Every puzzle has exactly one solution and can be solved by reasoning alone. No guessing, ever.
