Now with 3 lives and some code to stop asteroids spawning on top of the space ship :-) Press the green flag. Let me know if you find any bugs. Thanks and enjoy!
I wrote this to figure out how clones worked. My favourite bit is the motion of the spaceship. I knew how to do that from this course: https://www.coursera.org/course/interactivepython which I highly recommend if you want to make a jump from Scratch to Python. The whole course is spent building games.
