I have just uploaded some files for the 0.6.0 pre-release of the game. The files include source code and a Windows binary created from the Git revision from yesterday. The instructions for compiling the source code can be found from our wiki or the README file inside the package.
The game has received very little testing as of late, despite there being an abundance of major changes since the last release. Hence, it would be great if people could give the pre-release a try and report back whether it worked. In particular, I am interested in knowing whether there is crashing, whether graphics work on different setups, and whether the Windows binary works in versions of Windows newer than XP.
If things go as planned, I'll release 0.6.0 once Linux Mint 13 is out and I have tested and packaged the game on it. Getting bug reports or confirmation on the pre-release working before that would help a lot with the release work.
