I've made the following improvements to address your issues:
### 1. Fixed the Firing Mechanism:
- Completely rewrote the shooting function to properly create and track bullets
- Added a separate `updateBullets()` function that handles bullet movement and collision detection
- Bullets now properly travel through the scene and can hit enemies
- Added immediate hit detection using raycasting when firing
- Bullets are now visible and travel in the correct direction
### 2. Added 2D Map Overview:
- Created a new map overview canvas at the top center of the screen
- This provides a larger, more detailed top-down view of the entire maze
- Shows walls (gray squares), enemies (red circles), pickups (green circles), and player (green circle with direction)
- The map overview is larger and more detailed than the minimap in the corner
- Added a title "MAZE OVERVIEW" above the map
### Additional Improvements:
- Fixed the bullet physics to ensure they travel in the correct direction
- Improved collision detection for bullets with both walls and enemies
- Added bullet cleanup when they travel too far or hit obstacles
- Enhanced the visual feedback for shooting
- Maintained all previous features (30-second enemy spawn, reversed controls, etc.)
The game now has a fully functional shooting system where bullets are visible and properly interact with the environment. The 2D map overview provides a clear strategic view of the entire maze, making it easier to navigate and plan your movements.
