Built a Java implementation of Tetris using an object-oriented, event-driven design. Developed a lightweight game framework (World + BigBang) to handle the main loop, keyboard input, timed ticks, and rendering, then implemented core Tetris mechanics including collision detection, piece rotation, line clearing, scoring, and game termination logic.

• Real-time gameplay loop with timed “ticks” and keyboard controls (left, right, down, rotate)
• Piece generation and rotation system using pre-defined configuration matrices for each tetromino
• Line-clear logic with row shifting and score tracking
• Rendering pipeline using Java Graphics/Graphics2D with per-tetromino coloring
• Game-over detection based on board fill height / spawn constraints
