Hosted on sourceforge ugh. Seems quite a few of these open source revivals have been written in Java (possible mild confirmation-bias here.)
I agree that sourceforge is a scumbag company now, but what's the alternative for people who want a place to host binaries, source code, and user forums?
At the time, I'm not sure there really were better options than Java for a cross-platform open-source game like this. Maybe Python with PyGame.
