Finishing up the updates to my older games, I have just put up an Intel build of Asteroid Rally. This makes the game run better on Intel-based Macs, which is almost every Mac sold from 2006 onwards. I also updated the contact information.
The original PowerPC build of Asteroid Rally is still available for older Macs.
Asteroid Rally is far from my best game but can be kind of mesmerizing to play it full-screen with the in-game music. Or, if you prefer your own music, I recommend picking something ambient. Enjoy!
