+# Abstract
+Game name : Super Mario Bros

+
+# Game Introduction
+Super Mario Bros is a classic 2D side-scrolling platformer developed by Nintendo. Players control Mario, a plumber, as he runs and jumps through various levels to rescue Princess Peach from the villain Bowser. The game features enemies, obstacles, hidden secrets, and power-ups, making it one of the most iconic and influential video games in history.
+
+# Development Timeline
+
+### Phase 1: Planning & Physics Foundations
+**Week 2: Concept & Requirements**
+- [ ] Define "Mario Logic": Gravity constants, terminal velocity, and jump impulse values.
+- [ ] Setup C++ environment: SFML linking, directory structure, and CMake configuration.
+- [ ] Sketch the "Game Loop": `HandleInput` → `Update(dt)` → `Render`.
+
+**Week 3: OOP Design & Architecture**
+- [ ] Create Class Diagram: `Entity`, `Player`, `Enemy`, `Tile`, `Camera`.
+- [ ] Define Inheritance Hierarchy: `Entity` → `DynamicEntity` (Mario/Goomba) and `StaticEntity` (Blocks).
+- [ ] Establish the `GameManager` to coordinate state transitions.
+
+### Phase 2: Core Mechanics & Prototyping
+**Week 4: The Kinematic Player**
+- [ ] Implement horizontal movement with acceleration/deceleration logic.
+- [ ] Implement the variable jump (height depends on button hold duration).
+
+**Week 5: Tilemap & Static Collision**
+- [ ] Implement a `TileMap` class for rendering levels efficiently.
+- [ ] Implement AABB Collision Detection for solid ground and walls.
+
+**Week 6: Combat System (Stomp Logic)**
+- [ ] Implement vertical collision checks: Detect if Player is falling while colliding with an enemy's top bound.
+- [ ] Handle Player state changes (Small Mario vs. Big Mario hitbox scaling).
+
+**Week 7: Items & Blocks**
+- [ ] Implement `QuestionBlock` and `Brick` logic (breaking vs. bumping).
+- [ ] Create item classes: Mushrooms and Coins with their own simple physics.
+
+**Week 8: Level Scrolling (The Camera)**
+- [ ] Implement an `sf::View` based camera system.
+- [ ] Implement "Camera Locking" to prevent the screen from scrolling backward (classic NES style).
+
+### Phase 3: Expansion & Polishing
+**Week 9: Enemy Variety & AI**
+- [ ] Add different enemy types (Goombas, Koopas) using polymorphism for unique behaviors.
+- [ ] Implement "Pit Deaths" and boundary checking.
+
+**Week 10: State Machine & UI**
+- [ ] Add Start Menu, Pause, and Game Over screens.
+- [ ] Display HUD: Score, Coin count, World number, and Timer using `sf::Font`.
+
+**Week 11: Sprite Animations**
+- [ ] Implement an `Animation` manager to handle frame-switching for run, jump, and idle cycles.
+- [ ] Handle sprite flipping (texture rect mirroring) based on movement direction.
+
+**Week 12: Level Expansion & Loading**
+- [ ] Implement a File Parser to load level layouts from `.txt` or `.json`.
+- [ ] Add the "Flagpole" logic to trigger level completion and score calculation.
+
+**Week 13: Advanced Sound & Feedback**
+- [ ] Integrate Sound for jumps, stomps, and power-ups.
+- [ ] Add background music using Music with looping logic.
+
+**Week 14: Debugging & Refactoring**
+- [ ] Refactor code for Encapsulation (ensure no public member variables).
+- [ ] Fix "Wall Clipping" and "Corner Catching" physics bugs.
+
+### Phase 4: Testing & Finalization
+**Week 15: Playtesting & Balance**
+- [ ] Fine-tune physics constants (friction/gravity) for the best "game feel."
+- [ ] Ensure level difficulty progression is balanced.
+
+**Week 16: Demo**
+- [ ]   Add visual feedback (particle effects for breaking bricks).
+- [ ] Ensure smooth transitions between Game States.
+
+**Week 17: Demo**
+- [ ] Demo
+
+**Week 18: Submission**
+- [ ] Demo
