What is a Clicker Game?

A clicker game, also known as an incremental game, is a genre where the primary mechanic involves clicking on objects to generate resources or points. These games typically feature:

• Simple Core Mechanic: Click to earn points or currency
• Progression System: Use earned currency to buy upgrades
• Idle Elements: Automatic resource generation over time
• Exponential Growth: Each upgrade significantly increases earning potential

Popular examples include Cookie Clicker, Adventure Capitalist, and Clicker Heroes. The beauty of clicker games lies in their simplicity – they’re easy to understand but surprisingly addictive due to their satisfying progression systems.

Getting Started with Scratch

Before we begin coding, make sure you have access to Scratch. You can use Scratch online or download the offline version. For this project, we’ll be creating a planetary-themed clicker game where players click on a growing planet to earn resources.

What You’ll Need:

• Access to Scratch (online or offline)
• Basic understanding of Scratch coding concepts
• About 2-3 hours to complete the project
• Patience and creativity!

Setting Up Your Game Environment
