Scratch | Project | running for life

This is what my super 7 year programmer daughter made today. I am mostly reduced to the “Can you find the music of God Save The Queen?” support role. For the rest of it I just point her in the right direction as to how to get things to work how she wants. The controls are a bit quirky (she couldn’t figure out jumping so you have to switch from right arrow to space bar to get past the hurdles) – the ideas are all hers. I love the medal ceremony with 4th place crying in the corner.
