I’m building a casual, endlessly scrolling runner in a bright fantasy world and I need an experienced Unity developer to take it from concept to a fully playable prototype. The core loop is simple—dodge obstacles, collect pickups, and chase ever-increasing speed—but I want it delivered with polished 3D visuals, smooth mobile performance, and clean, well-commented C# code so new content can be added later without headaches. Here’s what I expect: • A Unity project set up for Android and iOS builds, using lightweight shaders so we keep frame rates high on mid-range devices. • Modular lane-based runner mechanics (jump, slide, strafe) tied to touch and keyboard controls. • Procedurally spawning track pieces and fantasy-themed obstacles that vary difficulty over time. • Basic UI with start, pause, game-over, and score screens plus simple sound hooks. • Clear documentation explaining code architecture, custom inspectors, and how to drop in new 3D assets. If you’re comfortable working in recent Unity LTS, follow SOLID patterns, and can share at least one similar mobile game you shipped, I’d love to see your work and discuss timelines.
