I’m developing a new puzzle experience called “Blok” and need a skilled game developer to turn the core idea into a working Android build. Scope • Design and code the main game loop for a single-player puzzle game. • Implement intuitive touch controls and a clean, lightweight UI. • Build a small set of sample levels that demonstrate the core mechanic. • Package the project as an APK and include full, well-commented source code (Unity or Godot preferred, but I’m open to other modern engines). Key Requirements • Runs smoothly on current Android devices. • Responsive controls and clear visual feedback for every player action. • Modular codebase so additional levels and features can be added later. I will provide the basic concept, asset guidelines, and any needed reference sketches. You bring the technical know-how to translate those ideas into a functional prototype, suggest refinements, and flag potential UX issues early. If you have shipped puzzle titles on Android before or can share relevant prototypes, that’s a huge plus. Let’s build “Blok” together—starting with a solid, playable foundation.

UNITY | ANDROID | PUZZLE GAME | MOBILE UI Hi, I’d be happy to help turn “Blok” into a solid playable Android prototype. The scope is clear, and I like that you’re focusing on getting the core mechanic and controls right before expanding the game. I can build the game in Unity, with a modular structure so new levels, mechanics and features can be added without rewriting the core systems. I’ll handle the main puzzle loop, touch controls, lightweight UI, visual feedback and the initial sample levels. I’ll also optimize the build for current Android devices and provide the complete Unity project with a ready-to-test APK. I’ll also pay attention to small UX details such as touch response, feedback, level difficulty and restart/undo flows, because these make a big difference in puzzle games. Once you share the core concept and sketches, I can suggest improvements before development starts and give you a clear timeline for the prototype. Thanks! Purnima

Hello, Your requirement for responsive touch controls and clear visual feedback on current Android devices shows you understand that puzzle games live or die by how they feel in hand. Building a modular codebase now prevents costly rewrites when you add levels later. We would start by implementing the core game loop for Blok with intuitive touch handling and lightweight UI using Unity or Godot based on your preference. Our team has delivered React Native mobile apps and shipped iOS and Android builds, so we know how to package clean APKs with well-commented source code that other developers can extend. We will build sample levels that demonstrate the core mechanic convincingly, flag UX issues early through iterative testing, and maintain conservative timelines throughout development. We work against milestones to keep progress transparent. Do you have a preferred engine between Unity and Godot, or should we recommend based on the specific puzzle mechanic? Share your concept sketches and asset guidelines and we will outline the initial prototype architecture before coding begins. DevDro

⚠️ IF YOU'RE NOT HAPPY YOU DON’T PAY ⚠️ I think we’re a strong fit for Blok. I’d focus first on making the core puzzle mechanic feel responsive and satisfying before expanding the level set or adding unnecessary features. I’d recommend Unity or Godot with a modular level architecture, touch-first input, clear visual feedback, and reusable puzzle components so new mechanics and levels can be added without rewriting the game loop. I’d first review your concept and reference sketches, prototype the core interaction, and validate it on Android before polishing the UI and sample levels. You’ll receive the tested APK, complete source project, and commented code ready for continued development. Multiple 5-star reviews on game development, Android applications, and interactive software projects. I’d love to chat about your project! The worst that can happen is you walk away with a free consultation. Regards, Chris

Hi, The phone-number database you described — import from Google Contacts, CSV, or vCard, then a simple search-and-add interface for your workers — is a clean, focused scope. I can build it as a lightweight PHP/MySQL application with a straightforward frontend that does exactly those three things and nothing extra. My approach: a small MySQL table for normalized phone records (number, name, source, tags), a PHP backend handling the three import paths (Google OAuth + People API, CSV parsing with league/csv, vCard parsing with jhassine/vcard-parser), and a single-page search UI that returns "found" or "not found — add new" in one flow. I'll add basic session auth so only your workers can access it, and sanitize all inputs to prevent injection. I've built similar contact-management tools before — most recently a Laravel-based CRM module that ingested 15k+ records from mixed CSV/vCard sources and exposed a searchable admin grid. The tech stack here is simpler (vanilla PHP or Slim if you prefer structure), but the import/parsing logic is the same work I've already done. Your budget range tops out at $250; I'd propose $220 fixed for the complete deliverable, delivered within 5 business days from kickoff. That covers the import pipelines, search UI, auth, and a brief handoff so you can deploy it on your own server. One question: do you already have a Google Cloud project set up for the People API, or should I guide you through creating the OAuth credentials? Albert C.

The biggest risk in developing "Blok" is getting the controls wrong. If players struggle with touch responsiveness, they'll lose interest fast. A poor user experience can sink even the best game ideas. That's why I'd prioritize implementing intuitive touch controls right from the start. It’s essential to make every action feel smooth and rewarding, giving players clear feedback. I’d start with the core game loop, ensuring it’s modular. This way, adding new levels later feels seamless. Regular revisions would be part of the process, allowing us to refine mechanics and address any UX issues early on. Have you set a deadline for the prototype? Are there specific asset guidelines I should keep in mind?

Hello, The need for a modular codebase that allows additional levels and features later means the prototype architecture must separate core mechanics from content data cleanly. Over-coupling these layers now creates technical debt that slows every future update. I'd start by translating your Blok concept into a minimal game loop that isolates the puzzle logic from level definitions and UI rendering. I have built small-business applications and worked extensively with Python, so I understand how to structure code for extensibility even in rapid prototypes. I will implement touch controls with immediate visual feedback, build sample levels that prove the core mechanic works, and package everything as a tested APK with thorough comments. The foundation will support adding new content without touching core systems. Are the puzzle mechanics grid-based, physics-driven, or something else entirely? Send over your reference sketches and I will propose the most efficient code structure for your specific gameplay before writing any logic. Ross

The main technical decision is between Unity and Godot. Godot is lighter and easier to get started with for a prototype, so I would pick Godot. I will build the main game loop in GDScript. The UI will be built using Godot's built-in Control nodes, so it is clean and lightweight. Touch controls will be implemented using the Input events and gestures, providing responsive controls and clear visual feedback for every player action. A small set of sample levels demonstrating the core mechanic will be created. The project will be packaged as an APK and include full, well-commented source code. The brief leaves the exact input method for moving blocks underspecified. I would assume swiping to move blocks until told otherwise. Track record on here: 100% on time, 100% on budget, 5.0 across 8 reviews. My focus is Android App Development and Mobile App Development. What do you consider the minimum Android API level this prototype needs to support? Send over the basic concept, asset guidelines, and any needed reference.
