Knowzzle: Kids Puzzles & Quiz

- Major art overhaul — replaced flat icon-style art with rich, hand-illustrated artwork across 12 of 16 categories: Animals, Ocean, Space, Fruits, Birds, World Flags, Insects, Music, Sports, Vegetables, Vehicles, and Nature. Most of the app looks substantially different now. - 10 new puzzles added, each with its own facts and quiz question: Bear, Deer, Red Panda, Seahorse (Ocean), Sparrow, Kingfisher, Woodpecker (Birds), Harmonica (Music), Cricket Bat (Sports), Bottle Gourd (Vegetables). - New: adjustable puzzle difficulty. A simple Easy/Medium/Hard control on the home screen now controls piece count (2×2/3×3/4×4) across the whole app, instead of being fixed per puzzle — you can make things easier or harder anytime, and progress is never lost when you switch. - New: a friendly "ready for more?" nudge — once every puzzle is finished at the current difficulty, a one-time, dismissible prompt suggests trying the next level up. Purely optional, never automatic. - "For Parents" is now easy to find — moved from a small footer link to a clearly visible spot near the top of the home screen. Same simple math-question gate as before, just easier to locate. - Fixed: Daily Challenge streak bug — replaying an already-completed puzzle as that day's featured Daily Challenge now correctly counts as done and updates your streak (previously it silently didn't). - Daily Challenge stays fresh longer — it now draws from your child's actual unlocked puzzles as they progress, instead of cycling through the same small starter set. - Minor category cleanup — removed a couple of puzzles that didn't fit their category (Microphone from Music, Trophy from Sports, and two flowers/a mushroom from Nature). - App size reduced
