Updated Basic Enemy Animation Spawn Animation: The enemy smoothly fades in or scales up upon entering the screen. Downward Movement: Moves straight down at a fixed speed. Side-to-Side Drift: Slightly drifts left and right while descending, making it harder to hit. Destroy on Exit: Gets removed when it moves off-screen. Wave-Based Spawning: A finite number of basic enemy ships spawn per wave. Wave Transition: After all enemies in a wave are destroyed, the next wave starts with a short delay. ↪💡 Consider importing and using the following plugins: @upit/tween.v1

Create a 2D space shooter game where the player pilots a high-tech spacecraft to defend the galaxy from waves of alien invaders and powerful bosses. The game should have classic arcade gameplay with modern visuals, smooth animations, and immersive sound effects. Game Features: Core Gameplay: The player's spaceship automatically shoots while the player controls movement (drag/swipe or joystick). Enemies appear in waves with increasing difficulty. Each level ends with a boss fight, requiring strategy to defeat. Enemy Types: Basic Drones – Weak but attack in numbers. Heavy Fighters – Move slowly but deal high damage. Fast Attackers – Swift movement, difficult to hit. Alien Motherships – Large bosses with unique attack patterns. Upgrades & Power-Ups: Weapon Upgrades – Spread shots, homing missiles, laser beams. Shields – Temporary invincibility. Speed Boosts – Increases maneuverability. Bombs – Destroys all enemies on screen. Graphics & Effects: Neon-style futuristic spaceship designs. Explosions and particle effects for impacts. Dynamic backgrounds with stars, asteroids, and cosmic elements. Game Modes: Endless Mode – Survive as long as possible. Story Mode – Complete missions to unlock new ships and weapons. Boss Rush Mode – Face all bosses in succession. Monetization (Optional): Rewarded ads for extra lives, power-ups. In-app purchases for new ships, skins, and weapons. Sound & Music: Futuristic, intense background music. Laser shooting and explosion sound effects.
