🎮 Watch your future game 🎁 Try Lessons 0 + 1 free Get full access 🔑 Enter passwordGalaxy Defender is a self-paced Python course designed for kids ages 7–16. No prior coding experience required — every concept is taught inside the game your child wants to build.
💡 About ages 7–9: the youngest readers will get the most out of the course when an adult sits with them for the first 2–3 lessons (to read the explanations aloud and help with typing). From Lesson 3 onwards most confident readers can self-pace with light check-ins.
Press SPACE inside the game window, then use the arrow keys to fly your cyan starship and SPACE to shoot. Survive long enough to score 30 hits and you win. Every part of this game is built across the 10 stages of the course.
💻 Best on a laptop or desktop. The in-browser coding editor uses your keyboard, so phones and tablets aren't recommended.
