📜 Game Instruction

Earth is under attack! Take control of the planetary defense cannon and repel the alien invasion.

🎯 Objective

Your mission is to score 2000 points to successfully defend the planet and win the game. The invasion will succeed and the game will be over if you let 5 alien ships escape off-screen, or if you run out of ammunition.

⌨️ Controls

Move Mouse: Move the crosshair to aim the defense cannon.
Left Click: Fire a projectile at the alien ships.
'R' Key: Press 'R' at any time to restart your mission.

👾 Enemies & Gameplay

Alien ships will fly in from the right side of the screen in waves. They come in different sizes:

Small Ships: Fast and nimble, worth 10 points.
Medium Ships: A standard threat, worth 20 points.
Large Ships: Slow but tough, worth 30 points.

Watch out! Larger alien ships can consume smaller ones, growing even bigger and becoming worth more points. Target these behemoths for a massive score boost!

💡 Tips & Strategies

Aim Ahead: Lead your targets, especially the faster-moving small ships.
Conserve Ammo: You only have 20 shots. Make them count! Running out of ammo is a guaranteed loss.
Prioritize Threats: Focus on preventing ships from escaping to avoid losing the game.
Exploit the Food Chain: Look for opportunities where large ships are about to consume smaller ones. Hitting the big one after it has grown can be very profitable.

Good luck, Commander! The fate of Earth is in your hands! 🚀
