+# Decay Protocol
+
+**A fast-paced survival arcade game where the floor crumbles beneath your feet.** *Made with Unity 6 & C#*
+
+![Game Screenshot](link_to_screenshot_here.png)
+
+## 🕹️ High Concept
+You are a rogue process in a dying mainframe. Every step you take corrupts the memory grid, causing the floor to disintegrate into the void. 
+* **Never stand still:** Idleness is death.
+* **Watch your step:** You create the holes you must navigate.
+* **Survive the purge:** Hunter processes and cleaning drones are trying to delete you.
+
+## 🎮 Controls
+* **WASD / Arrow Keys:** Move
+* **Space:** Jump / Air recovery (Includes Coyote Time)
+* **R:** Restart (After death)
+
+## ✨ Key Features
+* **Procedural Decay:** A "Swiss Cheese" map mechanic where every tile touched falls after 0.5s.
+* **Dynamic Difficulty:** Tile decay speed and Enemy spawn rates increase as your score climbs.
+* **Combo System:** Chain "Data Orb" collections within 2 seconds to multiply your score.
+* **Power-Up System:**
+  * 🟡 **Speed Boost:** Move faster.
+  * 🟢 **Hover:** Immunity to gravity/holes for a short time.
+  * ⚪ **Light-Footed:** Walk without breaking tiles.
+  * 🔵 **Time Slow:** Slows down world time (Matrix style).
+* **Audio-Reactive Visuals:** The neon grid pulses in sync with the BPM of the soundtrack.
+
+## 🛠️ Technical Architecture
+This project was built using a **Clean Architecture (Ports & Adapters)** approach to separate game logic from the Unity Engine API, ensuring testability and cleaner code.
+
+* **Core Domain:** `GameSession` manages the state, scoring, and rules purely in C# (no MonoBehaviours).
+* **View Adapters:** `TileViewAdapter` and `PlayerController` handle the visual representation and physics.
+* **Pooling System:** Custom `TilePool` to handle the high-frequency creation and destruction of grid tiles without GC spikes.
+* **Input System:** Built on the new Unity Input System package.
+* **Juice:** Heavy use of `LeanTween` for UI bounce, camera shake, and emission pulsing.
+
+## 🔧 Installation
+1. Clone this repository.
+2. Open with **Unity 6**.
+3. Open scene: `Assets/Scenes/Game.unity`.
+4. Press Play.
