I just build a Debian package for you so its easier to install. This is not an official one. I try to get it into the apt system but thats not so easy and takes time.
The final version 0.3.3 is now released.
It is considered bug free and and if i don't hear otherwise (File bugreports) it is unlikely that an update will be released.
This is my first release of the game. Its still beta and active development is still under way.
My project management site:
Please help and report bugs and stuff and a clear way to reproduce it.
You can use the ticket system on the site for that.
Also look into the gallery for some nice pictures. (under "Hosted Apps")
