Nice. An easy mode with/preferencing shorter words and a smaller grid would be appreciated. It seems to work fine at 12x12 which would suit my kid.

I added options for short, medium, and long words. I tested at 12x12, at that size the amount of words it's required to place needs to be around ~20 from my testing, any more and it will spend a long time attempting to generate and get no where (a future enhancement to stop after a while). What do you think now?

Thanks. I think that makes it much more suitable for my kid.

I like that the page is simple and clean without ads/garbage. Depending what your goals are you could call it done.

Here are some more thoughts if you keep tinkering.

- Always produce a puzzle. If the request is for a small grid and a large number of words and it doesn't work, decrease the number of words and output that. The total number of words is not that important.

- Instead of a download image, update the displayed puzzle with the new image and add a download button. The image is no longer a preview, just call it the puzzle. Perhaps add a transition/something to highlight the update.

- Add a download PDF button. Dumping the image into a PDF with PDFsharp/whatever should be pretty easy. PDF children's activities sheet keywords etc are presumably helpful.

- Add a bit of padding between the letters and the boarder.

- Add a link/qr code to the image/background/metadata to give yourself some credit.

I’ll see what I can do! Fortunately that’s already built in but just not exposed to the UI. Thanks for taking a look.
