🛠 Technical Architecture: How I Built This Web Game

Instead of relying on heavy game engines like Unity or Godot, I engineered the core game loop from the ground up. This approach ensures the game remains a lightweight browser game with near-instant load times.

  • Rendering Engine: HTML5 <canvas> API utilizing a requestAnimationFrame loop for ultra-smooth motion.
  • Animation System: Custom spritesheet logic for fluid submarine and enemy movements.
  • Physics & Collision: Custom AABB (Axis-Aligned Bounding Box) collision detection and projectile math.
  • Mobile APK Version: To provide a native experience, I packaged this HTML5 game into an Android APK using Kotlin and WebView, featuring custom on-screen touch controls.

⚡ Key Game Features

  • High-Performance Rendering: Optimized for 60FPS to prevent lag, making it a top-tier JavaScript action game.
  • Dynamic Difficulty: Features "Normal" and "Hard" modes with scaling enemy AI and health systems.
  • Cross-Platform Play: Fully optimized for Desktop (Keyboard) and Mobile (Touch UI) play.
  • Visual Effects: Real-time particle explosions and parallax underwater backgrounds.

🚀 Roadmap: The Future of SimSea

As a scalable web game engine, the future of SimSea includes:

  1. Global Leaderboards: Compete with players worldwide.
  2. Boss Battles: Massive underwater entities with unique attack patterns.
  3. Google Play Store Release: A fully polished native Android version.
