Mobile Logic-Puzzle Game Development

I want to bring a brand-new logic-puzzle game to life for both iOS and Android. The concept centres on bite-sized brain-teasers that grow in complexity as the player advances, rewarding clear thinking rather than reflexes.

Here’s what I need:
• Full design and coding of the core gameplay loop (touch-based grid and node interactions, timed and untimed modes, level progression, hint system).
• Clean, intuitive UI/UX that feels native on iPhone, iPad and the main range of Android devices.
• Lightweight but polished 2D visuals, subtle animations, and an ambient sound set I can expand later.
• A level editor or straightforward JSON/XML layout so I can add new puzzles without redeploying the entire build.
• Basic analytics hooks, optional rewarded-ad placement and IAP for extra hint packs.
• Final builds uploaded to TestFlight and Google Play Console, plus clear instructions for future store submissions.

Acceptance criteria
1. Stable performance on iOS 14+ and Android 10+.
2. No critical bugs across a 50-level test batch.
3. Source code, assets, and build scripts handed over in an organised repo.

Unity, Godot or a well-structured native/Flutter approach are all fine by me—use whichever enables rapid iteration and long-term maintainability. Let’s create an engaging logic-puzzle experience that keeps players thinking and coming back for more.
