[Mild Spoilers ahead!] Cool idea, interesting game and definitely thought-provoking on how this kind of puzzle could lead you to the solution. Very cool that you did this in a day! I do crosswords semi-regularly and I completed this puzzle with liberal use of the “check” function. One hard part of the concept is that the clue doesn’t indicate which part of speech the solution is. (To be fair, sometimes crossword clues don’t either, but they typically do, and if they don’t, they almost always narrow it down). Part of the puzzle here is also that “a picture is worth a thousand words,” so the commonalities between the images are needed to guide the player to the correct solution. The AI worked against the puzzle a little at times in that regard, as, e.g., where a mallard and a goose are apparently pictured in the vertical word on the far left, which could lead one away from the answer, or where the images for the horizontal word across the top don’t seem particularly related to the word, and are probably referencing a movie that was made with that word as its title. The fact that that’s a hard word to make an image of is likely why the AI ended up leaning on movie images. Anyway, as you can tell I had fun doing this and thinking about it – nice work!!
