| Feature | Implementation Hint | |---------|---------------------| | Different tower types | Subclass Tower with different damage, range, color, cost | | Enemy types | Add faster, armored, or flying enemies | | Tower upgrades | Add upgrade cost, increase stats | | Particle effects | Simple explosions on enemy death | | Sound effects | Use pygame.mixer for shooting and death sounds | | Save/Load high score | Write to a text file | | More maps | Define different WAYPOINTS and grid restrictions | This script provides a fully functional tower defense game with a dark pixel aesthetic. It is modular, easy to modify, and serves as a great foundation for learning game development or creating your own unique TD game.
