I've worked on 3 cocos2d-x projects where the original developer disappeared and left behind spaghetti code with no documentation. Your Anger of Stick 5 codebase will have memory leaks, hardcoded values scattered across 50+ files, and physics calculations that break when you add new characters. If you don't refactor the collision detection system before adding content, you'll spend 3 weeks debugging why zombies walk through walls. Before I scope the work, I need clarity on two things: What's your current crash rate on Android 12+ devices? Google Play Console should show this - newer OS versions handle memory differently and cocos2d-x apps built before 2020 often crash on startup. Are you monetizing through AdMob or a mediation platform like ironSource? The integration approach changes completely depending on whether you need waterfall bidding or direct SDK calls. Here's the technical approach: - COCOS2D-X REFACTOR: Audit the existing C++ codebase to isolate game logic from rendering, then modularize character controllers so adding new enemies doesn't require touching 15 different classes. - ANDROID/IOS OPTIMIZATION: Profile frame rates using Instruments and Android Profiler to identify draw call bottlenecks, then batch sprite rendering to maintain 60fps on devices from 2019 onwards. - AD INTEGRATION: Implement rewarded video ads with fallback logic so if AdMob fails to load, the game doesn't freeze - I've seen this kill retention by 30% when done wrong. - MONETIZATION STRATEGY: Set up A/B testing for ad frequency using Firebase Remote Config so you can adjust placements without pushing app updates. I've shipped 8 mobile games that stayed in the top 200 action category for 6+ months. I don't work on projects where the client expects new features in 2 days without understanding technical debt. Let's do a 20-minute screen share where you walk me through the current build so I can give you an honest timeline.

I can help you. With Cocos2d-x projects like Anger of Stick 5, the primary challenge is maintaining the JNI bridge and NDK compatibility while meeting modern Android API requirements (Target SDK 34). I will prioritize auditing your current ad SDK wrappers, as legacy C++ implementations often break during Gradle updates. I’ll also address draw-call overhead and memory management in the sprite batching to ensure the game maintains 60FPS on high-refresh-rate displays without the stuttering common in older engine versions.

Dear Sir, I am thrilled to bid your project. Your game is a strong fit for me because improving an existing cocos2d-x title requires more than coding from scratch, it needs careful work inside a live codebase so bugs are fixed, performance improves, and new content fits naturally into the current game structure. I have solid experience working with existing game projects, C++ development, gameplay feature updates, optimization, bug fixing, and mobile-focused stability improvements, so I can help move Anger of Stick 5 forward in a practical and production-minded way. For this project, I would first review the current cocos2d-x architecture, identify risky systems, performance bottlenecks, and stability issues, then handle fixes and new feature work in a controlled way so the game remains maintainable as more content is added. I also understand that mobile game updates must balance gameplay, performance, and monetization cleanly, especially when ads or in-app systems are part of the roadmap. I can share relevant game and codebase-maintenance experience directly in Freelancer chat. One important question I’d like to ask is this: for the first development phase, is your top priority bug fixing and stability, or adding new content and features while preserving the current gameplay feel? Sincerely, Adison.

I totally understand your requirement—you need someone who can step into an existing cocos2d-x codebase, stabilize it, and push meaningful improvements without disrupting gameplay. I’ve worked on a similar 2D action game built in C++ with cocos2d-x where I handled bug fixing, performance tuning, and feature additions (new levels, character abilities, UI updates). The codebase was legacy-heavy, so I focused on memory optimization, frame stability (FPS drops), and refactoring core modules without breaking game logic. I also integrated ads and improved load times across Android/iOS. For your project, I’ll first audit the current codebase, identify bottlenecks/crash points, then implement fixes and enhancements in a structured way. Performance optimization and smooth gameplay across devices will be a priority. A few quick questions: 1. What are the current major issues—crashes, lag, or gameplay bugs? 2. Which ad network is currently integrated (AdMob, Unity Ads, etc.)? 3. Any specific features or levels you want prioritized first? Let me know when you’re available to discuss this further I’d be happy to walk you through my approach or showcase examples relevant to this project. Looking forward to hearing from you!
