Develop Mobile Puzzle Game

I’m looking for someone who can take my concept for a casual puzzle game and turn it into a fully playable mobile title. This is a complete game-development job—from shaping the core mechanic through to a polished build that can be uploaded to a store.

The essentials:
• It must run smoothly on current Android and iOS devices.
• Gameplay centers on engaging, replayable puzzle mechanics rather than action elements.
• Art style, audio, and UI should feel light, intuitive, and friendly to first-time players.

What I need from you:
1. A short, written game design outline so we agree on the loop, level progression, and monetization (ads or IAP if you recommend it).
2. An iterative prototype (Unity, Godot, or similar engine—whichever you are fastest with) so we can quickly test the fun factor.
3. Final build, source project, and basic documentation that explains scene structure, key scripts, and how to generate future levels.
4. An in-game tutorial or hint system so new players immediately understand “cara mainnya gimana”.

I’ll be available for quick feedback on each milestone and will supply any additional art references or puzzle ideas you might need. Let me know the engine you prefer and show me a puzzle game you’ve shipped before so I can gauge the fit.
