My Unity-based PC title is already playable, yet it still carries the rough edges left after the previous developer stepped away. I now need a seasoned Unity dev to step in, refine what exists, and push the project over the finish line. Scope of work • Re-skin the entire user interface, covering the main and options menus, every in-game HUD element, and the loading screens. I have fresh mock-ups ready; you’ll translate them into clean, scalable UI prefabs that behave consistently at different resolutions. • Implement a full ranking system—think season-based leaderboards with local and global views, automatic score submission, and basic anti-cheat checks. • Introduce a level progression system that unlocks content, ties into player profiles, and saves remotely. • Trim or expand minor gameplay features as we iterate (I’ll provide a detailed change log). • General polish: bug fixing, UX tweaks, performance profiling, lighting passes, and final build packaging for Windows. Acceptance criteria 1. All UI scenes match supplied designs pixel-perfect at 1080p and scale gracefully up to 4K. 2. Leaderboards persist data to my backend API and sort correctly by score, rank, and time. 3. Level system correctly saves and loads player progress across sessions. 4. Final Windows build runs at 60 fps on my target spec (i5-9600K / GTX 1060) with no critical errors in the Player log. Unity 2021 LTS is the current project version; please be comfortable working in that environment and with Git for version control. Once these milestones are complete, I’m open to retaining you for future seasonal updates.

Hi, This looks like a cleanup and finish-line pass, with the main risks being UI scaling across resolutions, leaderboard sync with the backend, and keeping player progress aligned between local and remote saves. With mockups and a playable build already in place, I’d approach it in layers: UI first, then progression flow, then ranking and polish. I work in Unity 2021 LTS and can take this from rough systems to a stable PC release. My first step would be refitting the UI and testing across resolutions, then wiring the season leaderboard, score submission, and save/load flow with backup checks and log-based bug fixing. After that, I’d profile performance, clean up lighting and HUD behavior, and package a Windows build that matches your target spec. Relevant experience includes rebuilding menus, HUDs, scalable UI prefabs, leaderboard flows, level progression saves, and fixing bugs while optimizing build performance. Timeline: I can review the current state quickly and begin with UI and core flow stabilization immediately after access is confirmed.

Hello, As a result of a detailed review of your project requirements, I fully understand that this is an existing Unity 2021 LTS PC title that needs refinement rather than a rebuild. I have experience with Unity/C#, Game UI, API integration, progression systems, Git workflows, profiling, debugging, and Windows optimisation. In my opinion, the key challenge is introducing the new UI, ranking, and progression systems without destabilising the existing gameplay. I would first audit the current project, then rebuild the supplied mock-ups as reusable resolution-independent UI prefabs, integrate season/local/global leaderboards with your backend API, and implement persistent profile progression/unlocks. I’ll then work through your change log, profiling, lighting, UX and bug fixes, targeting stable 60 fps on the GTX 1060 specification. I have a couple of quick questions. • Is the leaderboard/profile backend API already complete and documented? • Can you share the UI mock-ups and gameplay change log before the first milestone? I would be glad to discuss further details and am ready to start immediately. Looking forward to hearing from you. Best regards, Carlos.

⭐⭐⭐⭐⭐ Hi, I’ve worked on Unity projects where the core game was already playable but needed a proper technical and visual pass before release. Your situation is a good fit because this is more than a UI reskin—you need the existing systems cleaned up, connected together, tested, and packaged into a stable Windows build. I’d start by reviewing the current Unity 2021 LTS project, Git structure, existing UI architecture, backend integration, and performance bottlenecks. I’ll then rebuild the menus/HUD/loading screens from your mock-ups using scalable UI prefabs, followed by the seasonal ranking and leaderboard system with local/global views, score submission, sorting, and basic anti-cheat validation. For progression, I’ll implement profile-linked level unlocking with reliable remote save/load behavior and make sure it survives reconnects and new sessions. After the main features are complete, I’ll handle the smaller gameplay changes, bug fixes, UX polish, lighting, profiling, and final Windows packaging. I’ll work through clear milestones: project audit → UI → ranking/progression → gameplay fixes → optimization → QA → final build. Changes will be committed through Git so you can review progress without risking the existing project. I’ll also test specifically against your i5-9600K / GTX 1060 target and check the Player logs for critical errors before delivery. I’m available to start quickly and can continue supporting future seasonal updates.

Hello, You need to re‑skin the entire user interface and add a season‑based ranking system to push the title over the finish line. I’ll build the UI with Unity’s UI Toolkit, anchoring prefabs to a Canvas Scaler set to Scale With Screen Size so they stay pixel‑perfect at 1080p and gracefully scale to 4K. The leaderboard will use UnityWebRequest to post scores to your API, with a simple hash check to deter basic cheats. Do you have the backend API endpoint URLs and authentication method ready for the leaderboard integration? Looking forward to working with you. Bojan

I would love to help you cross the finish line with your PC title. With strong expertise in Unity C# scripting, UI scaling, and performance profiling, I am well-prepared to clean up the remaining rough edges and polish your build to a 60 fps standard on your target specs. Regarding the version, I primarily work in Unity 2022 LTS, but I am completely comfortable adapting to your project's current 2021 LTS environment (or handling a clean upgrade if preferred). I use Git for structured version control and can efficiently tackle your UI re-skinning mock-ups into scalable prefabs, wire up the remote progression system, and implement the season-based backend leaderboards with secure score handling. Before we kick off, I have a quick question: Is only the leaderboard feature hooked up to an online backend, or does the entire game require an online/remote connection during active gameplay? Looking forward to collaborating with you on this and future seasonal updates!

I’m ready to step into this Unity 2021 LTS project and help take it from playable to polished. The scope is clear: rebuild the UI around your supplied mock-ups, keeping every menu, HUD, and loading screen crisp, scalable, and consistent from 1080p through 4K; implement a reliable season-based ranking system with local/global views and backend submission; wire in level progression with saved player profiles; and iterate on gameplay, bug fixes, performance, lighting, and final Windows packaging until the build is stable on your target hardware. I’m comfortable working in existing codebases, inheriting unfinished work, and pushing through the “last 20%” that usually takes the most care. I also work cleanly with Git, so collaboration and milestone tracking stay organized while we refine the game. If you want, I can start by auditing the current project structure, identifying the highest-risk systems, and mapping the fastest path to a shippable build.
