Thanks a ton! Difficulty is a great question. After a few rounds of puzzles, I like to aim for an 85-90% completion rate and found that puzzles with around 30-40 characters or usually 10-15 words is the sweet spot. Smaller letter pieces can also up the ante. There is a seeded puzzle generator algorithm that handles puzzle layout and piece creation. There’s an option to create your own puzzles and it’s always a treat seeing the bee movie script get generated lol
