Added Coin-Poison Game

@@ -0,0 +1,13 @@
+Coin & Poison is a grid-based arcade game where players navigate a square character to collect coins while avoiding poison blocks.
+
+**How It Works:**
+
+Players move in four directions using arrow keys.
+Collecting coins increases the score; colliding with poison ends the game.
+The game ends when all coins are collected or the player hits a poison block.
+
+**Features:**
+
+Randomly spawned coins and poison blocks.
+Real-time score tracking displayed on screen.
+Simple yet engaging gameplay focused on reflexes and strategy.
