Anger of Stick 5: Zombie has already crossed 500 million downloads and still earns about $10 k every month, yet much of its codebase hasn’t been touched in years. With a focused round of Cocos2d-x updates we can lift performance, refresh gameplay, and unlock far higher revenue—so I’m opening the project to a committed partner rather than a short-term contractor. The work calls for someone whose day-to-day strengths are optimization and performance improvement, gameplay mechanics enhancement, and new feature development. Android is our first target because that is where nearly the whole audience sits; once we prove our refinements there we can port the same wins to iOS later if it makes business sense. Here is what the collaboration will look like: • Regular C++/Cocos2d-x code contributions pushed through Git, structured in small sprints. • An optimized Android build (arm64 + armeabi-v7a) at the end of each sprint that beats the current live version in frame rate, file size, and crash-free sessions. • A concise change log and performance report that lets us measure gains before hitting publish. Revenue sharing, creative direction, and release cadence are all on the table and will be defined together so both of us feel ownership and benefit from the game’s future growth. If you see the same potential I do and can deliver the technical polish to realize it, message me with a short note about your most impressive Cocos2d-x optimization story and let’s talk.

Hello, As a result of a detailed review of your project requirements, I fully understand the scope and expectations, especially around optimizing an existing Cocos2d-x codebase, improving performance on Android, and enhancing gameplay while maintaining stability. I have experience working on performance-critical systems and optimizing legacy code for better frame rates, memory usage, and crash reduction. I bring deep expertise in C++, Cocos2d-x, Android development, Game Development, and Git with over 10 years of experience. One of the key challenges in projects like this is improving performance without breaking existing gameplay, so I would profile rendering and update loops, optimize memory and asset loading, reduce draw calls, and implement incremental improvements with measurable FPS and stability gains across each sprint build. From a similar optimization project, I improved a legacy game by restructuring update cycles, optimizing sprite batching, and reducing unnecessary allocations, which resulted in smoother gameplay and lower crash rates on mid-range Android devices. I have a couple of quick questions. • Do you already have performance benchmarks (FPS, crash rate, APK size) from the current live version? • Are there specific gameplay areas or systems you want prioritized in the first sprint? I would be glad to collaborate long-term and contribute to scaling the game further. Ready to start immediately. Looking forward to your response. Best regards, Carlos

Hi there. Are current performance bottlenecks mainly CPU bound (game loop, physics) or GPU bound (draw calls, batching)? Do you have crash logs or ANR reports to prioritize fixes early? This is a strong opportunity. I would start with profiling, optimize rendering and memory usage, then improve gameplay systems and add features in controlled sprints. I worked on a similar Cocos2d-x project where performance drops and crashes were limiting growth on Android devices. I solved it by reducing draw calls, optimizing asset loading, and fixing memory leaks which improved FPS and stability significantly. I have solid experience in C++, Cocos2d-x, and mobile game optimization, so I can help push performance and revenue forward. Hope to discuss more on chat. Best, Hlib T.

Hello, I’m a seasoned C++ developer focusing on performance tuning and gameplay polish for mobile games. I’ve built, refactored, and optimized codebases with Cocos2d-x, delivering leaners builds, smoother frame rates, and more stable sessions on Android. My approach is hands-on and sprint-driven: small, measurable changes, Git-tracked, with clear impact reports after each cycle. I’ve led optimization efforts where smart refactors, asset/textures management, and platform-specific tuning reduced APK sizes and improved frame pacing, while keeping gameplay intact. I’ll apply the same discipline here: target ARM64/ARMv7a builds, shave load times, minimize crashes, and publish concise change logs that quantify gains for each sprint. I can own the technical work end-to-end and align with revenue and release cadence through transparent collaboration. Let’s start with a quick plan, then set a two-week sprint cadence to validate gains on Android first. Best regards, Billy Bryan
