Thanks for your interest. The project is alive, although a little stalled at the moment.
I'm kind of burned out because of my daytime job and I'm failing to kick myself into more programming in my spare time. But I'm sure it's only a temporary setback
Realistically, though, there are tons and tons of work to be done. For that reason I'm considering changing the way the development is organized and making the development more open, in the hope of luring some contributors to the project. I'm not thinking necessarily just programming, but perhaps some artistic stuff (demo assets, 2D art for the app, shaders...).
