That's a really cool version, but you need to give some invincibility when you respawn, otherwise one death can be equivalent to 2-3 if there happen to be asteroids in the middle area at the time.

It was fun to look at your source code. About 600 lines.

I really liked the arcade version of asteroids, so me and a friend wrote a version in PDP assembler for a class project. I wish I still had the source code, but let's just say it was not as compact (e.g., we had to do the video driver, random number generation, trig, etc.), and took a couple of weeks.

Although the basic OO design is the same, which is cool.

Asteroid collisions completely change the game! You also nailed that vintage look! Nice stuff! I'm diving into your source code for polygons in detail!
