🌊 SimSea: 2D Action Shooter

SimSea is a 2D underwater action shooter built entirely from scratch using Vanilla JavaScript and HTML5 Canvas. It features smooth sprite-sheet animations, particle effects, and a dynamic difficulty system.

To make the game accessible to mobile users, I also packaged the web engine into a native Android APK using Android WebView and Kotlin.

🛠 Technical Architecture

Instead of relying on heavy game engines like Unity or Godot, I built the core game loop from scratch to demonstrate a deep understanding of JavaScript performance and rendering.

• Rendering Engine: HTML5 <canvas> with Vanilla JavaScript.
• Animation: Custom spritesheet parsing for fluid enemy and player movements.
• Physics & Combat: Custom projectile math, collision detection, and particle explosions.
• Mobile Integration: Packaged into an Android APK using Kotlin and WebView, complete with on-screen touch controls.

⚡ Game Features & Mechanics

• Smooth 60FPS Rendering: Optimized canvas drawing to prevent memory leaks.
• Multiple Game Modes: Includes a "Normal Mode" with timed stages and a "Difficult Mode" featuring a health system, faster enemies, and suicide attackers.
• Power-ups & Progression: Dynamic item drops and level scaling to keep players engaged.
• Cross-Platform Controls: Full support for Desktop (Keyboard) and Mobile (Touch UI).

🚀 Future Roadmap

The architecture is designed to be scalable. Future updates will include Boss Battles, a persistent Save System using LocalStorage, and a full Google Play Store release.
