Arcade 2D Ship Shooter

A classic 2D arcade space shooter built with Python and Pygame.

Features

• Frame-Rate Independent: Uses Delta Time ($\Delta t$) so movement speed remains consistent across all monitor refresh rates.
• Balanced Movement: Vector normalization prevents faster diagonal movement.
• Modular Architecture: Clean separation of game logic across dedicated entity files.
• Dynamic Enemy Spawning: Automatic timer system using custom Pygame events (USEREVENT) to spawn incoming enemies at randomized screen positions.
• Collision Detection: Efficient sprite-group collision management for projectile hits and player damage.
• Memory Management: Auto-destroys off-screen projectiles and defeated enemies to conserve memory.
