    This was great, really fun logic throughout the solve. The rules on Penpa only mention rotation of the shapes, not reflection, which threw me off a little.

    We’ve clarified the rules on the Penpa post which had the Standard Battleships text mixed with other language.

    This puzzle was amazing. I got stuck half way through thinking rules of pentominous applied and this really threw me off. Luckily got it in the end
