2D Puzzle Game Development

I’m ready to turn a fresh puzzle-game concept into a fully-playable 2D mobile title for both Google Play and the App Store, aimed squarely at an adult audience. I need a developer (or small team) who can take the idea from paper to publishable product, handling everything from core mechanics and level logic to art polish, audio hooks, QA and store submission.

Cross-platform workflow is essential, so your proposal should specify the engine or framework you believe best suits the job—Unity, Godot, Cocos2d-x or any comparable toolchain that delivers smooth performance on mid-range Android and iOS devices. Tight, intuitive touch controls and a gradual difficulty curve that keeps adults engaged without feeling patronised are key design goals.

I’ll be looking closely at detailed project proposals that outline:
• Technical approach and chosen engine
• High-level game loop and feature set (levels, hint system, possible IAP pack, leaderboards, etc.)
• Milestones with estimated timelines for prototype, alpha, beta and store-ready release
• Asset production plan (art style, animation method, audio sourcing)
• Testing strategy for multiple screen sizes and OS versions
• Post-launch support or update roadmap, if offered

Acceptance criteria for final hand-off: Android APK + iOS IPA ready for store upload, complete and well-commented source code, all original or properly licensed assets, meta-data bundles (icons, screenshots, privacy policy links) and clear documentation for future maintenance.

If you can bring a polished 2D puzzle experience to life and back it up with a clear, structured plan, I’d love to review your proposal.
