I’m planning a mobile puzzle title built entirely in Unity for Android and need someone who can take the idea from concept to a polished .apk. The gameplay will revolve around 3D environments and physics-based challenges rather than 2D tile swapping, so solid experience with Unity’s 3D workflow, lighting, and mobile optimisation is essential. Because I don’t yet have art, animation, audio, or UI assets, you’ll be creating everything from scratch—models, textures, effects, sound cues, and menu screens—matching a cohesive, modern style suitable for mid-range devices. I’ll provide the core puzzle mechanics and reference sketches; you’ll translate those into playable levels, intuitive controls, and a short tutorial. Key deliverables • Fully functional Unity project with at least one complete puzzle world (five levels) • All original 3D assets, textures, materials, animations, and SFX packaged and source-file ready • Optimised Android build (targeting Android 8.0+, <150 MB) plus signed release-ready .apk I’ll sign off milestones after each world mechanic is integrated, assets meet the agreed visual standard, and builds run smoothly on test devices without frame-drops or crashes. If you know your way around Unity’s Addressables, URP, and mobile performance profiling, we’ll move quickly.
