Symmetry solves it all!!

Two hearts.

Loved it! Very nice :)

A tiny bit of guesswork when you get to the end but not too hard to figure out! Nice, mostly logical puzzle. Thanks! ~:)

Spoiler alert: No guessing if you know that it is symmetrical along the Y axis (side to side) and reverse image (negative image & mirrored) along the X axis (top to bottom).
This is very clever and really fun to solve! Thanks!

Very clever! :)

Thanks.

One unique solution. Thank you for the puzzle.

This puzzle is completely logical, but you may need temps for the bottom center to find the contradictions.
