Here's how the lessons work — takes 30 seconds to read.

Theory Panel (left)

Read the concept. Scroll down to Objective to see the checklist of what you need to do in this lesson.

Code Editor (center)

This is your game code. Find the YOUR CHOICE comments and change the values right next to them. That's your creative input!

Check button

When you've made your choices, click Check. It verifies your objectives. Keep editing and re-checking until all pass!

Your code carries forward through every lesson. Change a color in lesson 1 and it'll still be your color in lesson 5. By the end, you'll have a complete, custom game.
