📖 About the Project

The Inspiration

I’ve always been fascinated by "micro-competitive" communities—the groups of people who obsess over a daily Wordle or a high-score leaderboard. I wanted to bring that exact energy to Reddit. Bounce Streak was inspired by the simple joy of keep-it-up soccer, combined with the "Daily" hook that turns a simple game into a community ritual. I envisioned a game that wasn't just about skill, but about adapting to the "chaos" of the day.

What it does

Bounce Streak is a high-performance Reddit Devvit application—a "keep-it-up" soccer game designed for seamless play directly within your favorite subreddits.

• Daily Reset: Every 24 hours (UTC), the game generates a new set of physics modifiers. One day you might be fighting high horizontal wind; the next, you're dealing with increased gravity.
• Dynamic Challenges: As your score increases, the game responds with confetti, fireworks, and falling obstacles to test your focus.
• Community Loops: Record your best streak and share it directly into the post comments with one click to challenge your friends.

🛠️ Technical Strategy & Architecture

Dependency Selection

To meet the specific requirements of professional-grade 2D physics and complex game state management, I made several strategic technical choices:

• Core Engine: I chose Phaser 3.87 for its robust rendering and arcade physics capabilities.
• Physics & Logic Support: I imported Antigravity as a key dependency to handle specialized physics calculations and streamline the integration between the game loop and the React-based UI.
• Platform: I integrated the Reddit Devvit SDK to leverage native Reddit features like Redis storage and the comment-sharing API.

I Engineered the Game Mechanics

I spent significant time tuning the GameScene.ts to ensure the physics felt responsive yet challenging. I implemented a deterministic PRNG system based on the daily UTC date to ensure every user faces identical conditions:

$$Seed_{daily} = YYYYMMDD g_{active} = g_{base} \cdot \mu_g$$

I optimized the mobile experience with a custom 38px "Cushion Zone" (approx 1.2x ball width) for touch inputs, ensuring the game feels satisfying even on small screens.

Built With

Reddit Devvit SDK, React 19, Phaser 3.87, Antigravity, Google Gemini API, Redis, Express 5, Tailwind CSS 4, Vite 6, and TypeScript 5.8.

📋 Build & Deployment Profile

I configured the build pipeline using Vite 6 to handle the unique constraints of the Devvit environment. You can manage the project using these commands:

npm run dev          # Watch client, server, and Devvit playtest
npm run build        # Build optimized production bundles
npm run deploy       # Upload to Reddit developers portal
npm run launch       # Publish the app for community review
