The one thing that I didn't get was how he made the game restart when he pressed R at the game over screen. In the video he never shows how the code would work or pressing it at all, so I added the code myself as he never showed it. I added a instance event in the destroying event in the small asteroid code so every time a small asteroid gets shot, another big asteroid spawns making the game harder. https://drive.google.com/open?id=1IUvkBtyGBEHHqzN5c0lna9vwuHWPbuJD

Accidentally continued on to part 4... https://drive.google.com/open?id=1o03LRG9BhgFq16Pkp7zyVoIaaTpbDWpT I didn't run into any problems.

I didn't have an issues because the tutorial was very easy to follow. The one thing I wish I could have changed was the colour of the score but i don't know how. https://drive.google.com/open?id=1vEA68vtrbeT3UhEWmipmW4I49vNTl92X
