Project Name: prime-bubbles

1. Introduction

The prime-bubbles project is a mobile game application designed to deliver a fun and engaging bubble-shooting experience. Inspired by classic arcade games like "Bubble Shooter," this project aims to create a simple yet addictive gameplay loop where players shoot and pop bubbles to achieve high scores. The game will initially target the Android platform, with scalability to iOS in the future.

This document outlines the system requirements for prime-bubbles, ensuring a clear roadmap for development and implementation. The game will cater to casual gamers in India (IN) and globally, with a focus on lightweight performance, vibrant visuals, and smooth gameplay.

Theme

The game will feature a vibrant and cartoonish aesthetic with smooth gradients and playful animations. The bubbles will have a glossy, 3D appearance with subtle reflections.

6. Signature Design Concept

Interactive Bubble Universe

The home screen will feature an interactive bubble universe where bubbles float gently in a 3D space. Each bubble represents a menu option (e.g., Play, Settings, Shop). When a user taps a bubble, it "pops" with a satisfying animation, revealing the corresponding screen.

• Animations: The bubbles will bounce slightly when touched and emit a glowing ripple effect.
• Transitions: Smooth zoom-in transitions will occur when navigating between screens.
• Micro-interactions: Hovering over a bubble will cause it to wobble gently, inviting interaction.
• Background: A dynamic gradient sky that shifts colors based on the time of day (e.g., sunrise hues in the morning, starry night in the evening).

This design will create a memorable first impression and immerse players in the game’s playful world.

7. Non-Functional Requirements

• Performance:

  • Maintain 60 FPS for smooth animations.
  • Ensure the app size is under 70MB.

• Scalability:

  • Design the architecture to support future features like leaderboards and multiplayer modes.
