Vertical Shooter

Procedural enemy waves, arcade style, with a simple minimal look.

Controls:

• Shots inherit some vehicle motion (strafe adds lateral bullet drift)
• Big enemies can drop:
  • health packs (+1 health)
  • weapon upgrade (unlocks spray fire)
• X toggles single/spray after unlock (1 = single, 2 = spray)
• R restarts with a new procedural seed
• Enter restarts after game over
