Overview

This is a Tower Defense game developed using OpenGL, where players strategically place cannons to defend against waves of incoming enemies. Players need to plan their defenses carefully to survive increasingly challenging opponents.

This game was heavily inspired on the Club Penguin Mini-game System Defender.

Game Mechanics

Objective

The primary goal of the game is to prevent enemies from reaching your tower by strategically placing cannons along their path.

Cannons

struct CannonStats {
	Color color;
	CooldownMs cooldownMs;
	HealthPoints damage;
	Range range;
	HealthPoints cost;
};

Types of Cannons:
1. Tier A: Faster but worst damage and worst range
2. Tier B: Long Range but middle damage and rate
3. Tier C: Most Damage but worst rate and less range
Upgrading Towers: Players can spend resources to upgrade cannons, increasing their damage and range.

Enemies

struct EnemyStats {
	Color color;
	HealthPoints health;
	Speed speedUpMs;
};

Types of Enemies
- Tier A: Fastest but less health
- Tier B: Fast but average health
- Tier C: Slow but more health

Waves

Enemies spawn in waves, with each wave becoming progressively more difficult. Players must survive a set number of waves to win the game.

Resources

Players earn resources by defeating enemies, which can be used to build new cannons and upgrade existing ones.

Game Over Conditions

The game ends when the tower is destroyed.
