# Project Overview I am looking for a Unity developer to build the first MVP / vertical slice of a mobile app called **MIO**. MIO is a digital companion for children aged 3–8. The goal of this MVP is not to build a full game, but to validate the core emotional experience: **Egg → MIO hatching → first interaction → feeding → first reward → home screen** The app should feel simple, warm, child-friendly, and focused on emotional connection. # Target Platforms * Android * iOS * Portrait mode * Phones and tablets * Offline-first * No backend * No login * No ads * No in-app purchases for this MVP # Engine / Technology * Unity 6 * C# * 2D mobile project * Local JSON save system * Responsive UI for phones and tablets # MVP Scope ## 1.

Then we proceed to Milestone 2 This process repeats for each milestone. # Main Goal The main goal of this MVP is to test whether children emotionally connect with MIO. The MVP should answer one question: Will a child feel that MIO is their own digital friend? This is more important than adding many features.

Hi There!!! ★★★★ (Building a Unity-based emotional MVP for a child-friendly digital companion app with core interaction loop) ★★★★ Project understanding: I understand you need a Unity developer to build an MVP of the MIO app focusing on a simple emotional journey (Egg → hatching → feeding → rewards → home screen). The goal is not a full game, but a clean, warm, offline-first experience that validates emotional connection with the character. Services: ⚜ Unity 6 2D mobile project setup (iOS & Android) ⚜ Clean architecture with scene management ⚜ Boot, Tutorial & Home scene development ⚜ MIO character animation & interaction system ⚜ Drag & drop feeding system implementation ⚜ Friendship progression system (0–10) ⚜ Local JSON save/load system I have experience in Unity mobile game development and interactive character systems using C#, focusing on smooth UI/UX and lightweight architecture for MVP builds, bit expereince in 2D animation integration and save systems also. Plan is to first build core project structure and save system, then implement scenes flow, followed by character interactions, feeding system, wardrobe, and finally testing + polish for stable iOS/Android builds. I can start immediately and focus on a clean, scalable MVP structure for future expansion. Warm Regards, Farhin B.

Hi! I’m a Unity developer specialized in C# and mobile projects. I carefully read the full scope for MIO. I understand the goal of this MVP is to validate the emotional experience: Egg → hatching → first interaction → feeding → first reward → home screen, not to build a large game. I can help you build this vertical slice in Unity 6 with a clean and scalable structure, including Boot/Tutorial/Home flow, local JSON save system, MIO character states, simple animations, drag-and-drop feeding, friendship progression, wardrobe with persistent hats, responsive portrait UI, audio feedback, Android build, and final source delivery. Most of my work is in Unity. You can check my profile: my reviews are from Unity projects, I have 100% job completion and a strong rehire rate. About iOS: I can keep the project iOS-ready from the beginning, with responsive UI, touch input, portrait mode, safe area support and no locked dependencies. To keep the project efficient, I recommend doing Android builds during the early milestones and handling the actual iOS export/build validation in the final milestone. If a Mac/cloud build service, Apple Developer account, certificates, provisioning or TestFlight setup are required, those external costs/access should be provided by the client or handled as a separate approved cost. I’m comfortable working milestone by milestone following your structure and keeping the MVP focused on the core emotional connection. God bless you, Have a nice day!

With extensive Unity development experience, I understand the need to create a warm and child-friendly mobile app like MIO for children aged 3–8. My previous work in developing interactive and emotionally engaging applications aligns perfectly with the core experience you aim to validate. Could you share more details about the specific visual style or artistic direction you envision for MIO to enhance its emotional appeal? Regards, Yogesh Kumar

Unity and C# aren’t my stack—I build interactive mobile apps and prototypes in Flutter for iOS and Android. Your MIO concept with onboard logic, local save, and strong visual state fits Flutter, though animation tooling is different from Unity. I’ve shipped child-focused mobile flows with onboarding scenes, persistent character states, drag-drop, and reward systems. If you can pivot from Unity/C# to Flutter, I can build the full MVP as specified: clean save/load (JSON, local), responsive UI, portrait, cross-device, large touch targets, basic SFX hooks, and a structure ready for final assets. Are you open to Flutter if it delivers your UX goals? If yes, I can break down exactly how I’d structure the vertical slice. Pradeep

Hi, I’d be very interested in developing the Unity MVP for MIO. With 10+ years of experience in Unity (2D/3D), C#, mobile game development, and interactive child-focused applications, I specialize in building lightweight, emotionally driven MVPs that are structured for future scaling. Your scope is clear and well-defined, especially around the core emotional loop (Egg → Hatching → Interaction → Care → Reward). That kind of focused vertical slice is exactly how I approach MVP development. My technical approach: • Unity 6 + C# structured with clean, modular architecture (scenes + services separation) • Offline-first design using lightweight JSON save/load system • Mobile-optimized UI (portrait-first, scalable for phones/tablets) • Event-driven systems for feeding, friendship, wardrobe, and interactions • Animator-based character system for MIO (idle, tap reactions, feeding, happiness states) • Fully decoupled asset system so all visuals/audio can be replaced later without code changes Deliverables will include: • Complete Unity project with structured source code • Android build (APK/AAB) and iOS project files • Fully working MVP across all milestones • Documentation for setup and future expansion • No locked dependencies or restricted assets I’d be happy to start with Milestone 1 immediately and can also suggest small refinements that reduce risk while keeping the scope intact.
