Hey Everyone,
I'm a developer on the project.
We are going through an open-source reboot with Gosu, moving all development out onto Github, and the current site and release isn't 100% ready for prime time, but I guess it's too late for that now...
I'm happy to answer any questions anyone has.
Also, we are working on a web micro-framework called SparkGS:
http://sparkgs.github.io/
which is a wrapper around the excellent SparkJava library.
