Unity Mobile MVP Development – MIO Digital Companion App for Kids -- 2

# 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. Project Setup & Architecture

Developer must create:

* Clean Unity project structure
* Mobile-ready project setup
* Android configuration
* iOS configuration
* Basic scene management
* Basic app flow
* Local save/load structure

# Scenes Required

## Boot Scene

Responsibilities:

* Initialize app
* Load local save data
* Check if tutorial is completed
* Route user either to Tutorial or Home Screen

Flow:

If first launch:

Boot → Tutorial

If returning user:

Boot → Home

## Tutorial Scene

Tutorial flow:

1. User sees a glowing egg
2. User taps the egg several times
3. Egg cracks
4. MIO appears
5. MIO waves / reacts
6. User feeds MIO for the first time
7. MIO becomes happy
8. User receives first reward
9. First hat is unlocked and equipped
10. Tutorial is marked as completed
11. App opens Home Screen

## Home Scene

Home screen contains:

* MIO character in the center
* Friendship indicator
* Feed button
* Wardrobe button
* Simple child-friendly UI
* Large buttons
* Minimal text
* Icon-based interactions

# Core Features

## MIO Character System

MIO should support:

* Idle state
* Blink animation
* Wave animation
* Eating animation
* Happy animation
* Basic touch reactions

Touch reactions:

When user taps MIO, MIO should react with a small animation or sound.

Examples:

* Blink
* Smile
* Wave
* Happy bounce

# Feeding System

Simple drag-and-drop interaction.

Flow:

1. User taps Feed button
2. Food item appears
3. User drags food onto MIO
4. MIO eats
5. Eating animation plays
6. Happy animation plays
7. Friendship value increases
8. Progress is saved automatically

For MVP:

* Food is unlimited
* No food inventory
* No timers
* No replenishment system
* No shop

# Friendship System

Simple value from 0 to 10.

Rules:

* Feeding MIO increases Friendship by +1
* Friendship is saved locally
* Friendship should be visible as a simple progress indicator
* No complex leveling system is required for MVP

# Wardrobe System

MVP contains 3 hats:

* Hat_01
* Hat_02
* Hat_03

Requirements:

* Hat_01 is unlocked during tutorial as first reward
* Hat_02 and Hat_03 can be available in wardrobe
* User can equip and unequip hats
* Equipped hat must be visible on MIO
* Equipped hat must persist after app restart

# Save / Load System

Local JSON save.

Required saved data:

* Tutorial completed: true/false
* Friendship value
* Equipped hat ID

Example:

{
"tutorialCompleted": true,
"friendship": 3,
"equippedHat": "hat_01"
}

Save must happen automatically after important actions:

* Tutorial completed
* Feeding completed
* Hat equipped
* Friendship changed

# Audio

Basic placeholder SFX:

* Button click
* Egg crack
* Eating sound
* Happy sound

No voice acting required.

# UI / UX Requirements

The app is for children aged 3–8.

Important rules:

* Large buttons
* Minimal text
* Icon-based UI
* No complicated menus
* No deep navigation
* Positive visual feedback
* Soft animations
* Friendly colors
* MIO should be the main focus of the screen

# Assets

For MVP, placeholder assets are acceptable.

However, the project must be structured so that final assets can be easily replaced later.

Developer should support future replacement of:

* MIO character artwork
* Hats
* UI assets
* Animations
* Audio

Final production-quality art is not included in this development scope unless agreed separately.

# Deliverables

At the end of the project, I expect:

* Complete Unity project
* Full C# source code
* Android APK or AAB
* iOS project/build files
* All placeholder assets used
* Setup/build documentation
* No locked third-party dependencies
* No proprietary assets that prevent future development

# Payment Terms

The project should be completed milestone by milestone.

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.
