2D Platformer Game — Final Java Project (LibGDX)

Welcome to the final course project: a 2D platformer game created using Java and the LibGDX framework. The goal is to showcase gameplay elements (movement, jumping, enemy collision, coin collection) and apply at least 5 software design patterns.

Features

• Player can move left/right and jump using keyboard keys.
• Collect coins to increase score.
• Colliding with enemies reduces health.
• Player starts with 3 lives shown as hearts.
