The latest release was made on: October 24th which added support for native 64bit!
Now one of the team has created 32bit and 64bit .deb installers (so you no longer have to compile from source for Debian based Linux distros).
Only problem so far is that it doesn’t create a menu item for you and I have yet to be able to make one that works – I have reported this issue though so hopefully it can be resolved!
Edit – The team is working on the menu item issue.
The game works great though!
