Gizmo's Puzzles

 After all these years, I've finally done it. Just kidding, it took like 30 minutes on a crowded bus ride through the streets of Naples, Italy, during which I had the idea for this puzzle. Black squares are so limiting, so unneccessary. When the Greeks wrote the Arepo word square, did they use black squares? I don't think so. As I looked out at the beautiful night sky, I considered how my ancestors would have wanted crosswords to be done. I cursed Arthur Wynne for inventing the only limit to creativity in the crossworld. This is the natural progression of the crossword meta. I expect constructors to follow my lead first. I have a very long wordlist of 15 letter entries if anyone needs them (over 50,000 and growing as I come up with new word combos every day!) This puzzle functions as a themeless, but think of it as a themed puzzle, with the theme being innovation and discovery. After all, this is a record-setter, demolishing the previous record of 17. Eat my dust, Joe Krozel. S

 What's "up"? It's me, Gizmo Thwomp, here with a fairly simple 58-worder themed puzzle. I decided to take some inspiration from Lollapuzzoola pro  Will Nediger  and stack some theme entries. However, if you're not a fan of themes, please ignore all nine theme-related entries and solve it like a themeless.  Ta-ta, Gizmo

 Greetings, Today's puzzle is a fun, asymmetric themeless with some fun fill and clean crossings. Many thanks to the wonderful  Ada Nicolle  for contributing the bottom right 5x5. Thank you for the support, Gizmo

 Just another day at work. Nothing to brag about. Technically it's a 15 stack if you count the shorter answers, too. Sincerely, Gizmo

 You're all powerless to stop me.  Love, Gizmo

I have been asked to narrow down my theme density from last time, so this puzzle uses only 127 squares as theme material instead of last puzzle's 46. It's a 17x17 grid, so I think it's about equivalent. Cheers, Gizmo
