I’m building a cross-platform jigsaw puzzle app that should feel perfectly native on both iOS and Android. The core mechanic is classic jigsaw play, yet I want it elevated with thoughtful polish and smooth performance. Key gameplay and usability features I need implemented: • Multiple difficulty levels so users can start small and work up to 1 000-piece monsters • A simple way for players to load their own photos as new puzzles (customizable images) • Built-in timer and score tracking to encourage replayability and friendly competition What matters most to me is clean, maintainable code and an intuitive user interface that looks great on phones and tablets alike. Whether you choose Unity, Flutter, React Native or a similar framework, please make sure the final build meets Apple App Store and Google Play guidelines and is ready for submission. Deliverables 1. Complete source code with clear instructions for local build and store submission 2. UI/UX assets (sprites, icons, sounds) either original or licensed for commercial use 3. Play-tested, bug-free release APK/IPA or TestFlight build 4. Brief hand-off document summarising architecture, third-party libraries and how to add new puzzle packs in future If this sounds like your kind of project, I’m ready to move quickly. Show me examples of previous mobile games you’ve shipped—especially any puzzle titles—and let’s craft an addictive jigsaw experience together.
