In this Star Wars game, you are a TIE Fighter trying to get through an asteroid field. Use the left and right arrow keys to move. Press the up arrow key for hyperdrive, which takes 20 seconds to refuel. (The white things are stars, BTW. Not asteroids).
I got the idea of this game from the book "Star Wars Coding Projects" by Jon Woodcock. I tweaked it a lot, but the basic idea and coding are the same as from the book. The image in the background is from https://www.starwars.com/databank/death-star.
