4. Find and fix one bug
Change the left-arrow value to positive 10 on purpose. Ask your child to predict what will happen, then test it. Both keys now move the character right. Change the left-arrow value back to −10 and retest both keys. Explain the correction in one sentence: “The key chooses the script; the sign chooses the direction.”
5. Make it your own
Add a backdrop or change the greeting. Then try a starting position: add a “go to x: 0 y: 0” block after the green-flag event. Move the character and restart. It should return to the center. Change one thing at a time so you can tell which change caused a result.
