+# 2D Platformer Game with Pygame
+
+This is a simple 2D platformer game created using Pygame, where the player can move, jump, and collect coins placed on platforms. The game includes a scoring system where points are earned by collecting coins.
+
+## Features
+
+- **Player movement**: Move left and right using arrow keys, jump using the space bar.
+- **Multiple platforms**: Platforms are generated at random positions and heights.
+- **Coin collection**: Coins are placed on platforms, and the player earns points by collecting them.
+- **Score display**: The player's score is displayed on the screen.
+
+## Controls
+
+- **Left arrow**: Move left.
+- **Right arrow**: Move right.
+- **Space bar**: Jump.
+
+## Installation
+
+### Requirements
+
+To run this game, you need to have Python and Pygame installed on your machine.
