🎲 Tetris Game (WPF / C#)

This is a Tetris game built entirely from scratch using C# and WPF (Windows Presentation Foundation). It features custom block logic, a scoring system, held pieces, and colorful sprite-based graphics.

This was a personal project to strengthen my object-oriented programming skills and deepen my understanding of game loops, UI rendering, and state management in C#.

✨ Features

• Classic Tetris rules with rotation, hold piece, and scoring
• 7 tetromino types (I, J, L, O, S, T, Z) each with rotation logic
• Grid-based collision detection
• Block queue & held piece functionality
• Custom game loop
• Visual design using PNG tile sprites

🏆 Gameplay Highlights

• Score increases by number of cleared rows
• Game ends when new block can't spawn
• You can rotate CW/CCW, move side to side, and hard-drop
• Hold a piece to save for later (one-time per drop)

---

📋 Learnings & Challenges

• Implemented OOP principles through abstract classes & inheritance
• Built logic-heavy systems like block collisions, rotations, and queue shuffling
• Gained confidence in WPF rendering and UI threading

---

✨ Future Improvements

• Add sound effects
• Implement ghost preview of where block will land
• Add level progression with increasing speed
• High score tracking

🚀 Made With Love

Built by yours truly to level up my C# and game dev skills. Feel free to fork it, try it, or reach out if you want to roast my game logic haha.
