 `Play` → `Collect` → `Grow` → `Avoid` → `Fail` → `Restart`
 
 The simplicity of the mechanics allows for immediate understanding, while increasing difficulty creates tension and replayability.

+```
+What are the game elements (e.g. characters, world, interface) and how will they be implemented in code (e.g., modules, classes, objects, functions)? Feel free to use diagrams, flow-charts or any other visual representation to show your plan.
+```
+
+The game will feature a dark 3D environment with glowing spheres as the main visual elements, creating a clean and immersive experience.

+### Game Elements
+
+- **Player**: glowing sphere with trailing body segments
+- **Orbs**: collectible glowing spheres
+- **Obstacles**: larger objects that cause collision
+- **World**: bounded arena on a flat plane
+- **UI**: score, best score, start and game over screens
+
+### Code Structure
+
+The game will be organized into simple modules:
+
+`main.js`  
+ ├── `GameManager`  
+ ├── `Player`  
+ ├── `Orb`  
+ ├── `Obstacle`  
+ └── `UI`
+
+- **Player**: movement, growth, collision
+- **Orb**: spawning and collection
+- **Obstacle**: collision handling
+- **GameManager**: game state, score, restart
+- **UI**: display elements
+
+### Gameplay Flow
+
+![](flow.png)
+
+### Technical Approach
+
+- Built using **Three.js** for 3D rendering
+- Movement constrained to a plane for simplicity
+- Objects managed using classes and arrays
+- Collision detection using distance checks
