Also there’s a new PC version. The new version is numbered 55. And there are bunch of small changes. Nothing radical, but few bug fixes and improvements. Biggest change has been that the game now uses OpenGL instead of DirectX. Which means that you’ll probably won’t see any kind of actual change in the game. Unless the OpenGL implementation breaks the game for you. Which might happen… If that happens I’m sorry. The demo on the site is based on the older DirectX version so it’s not a good way to test if the actual game works on your system. We’re working on getting the demos up to date and on the site. Also we’re working on getting the demo for the other platforms as well.
For the Mac and Linux builds I have to thank Dennis Belfrage, Jani Hast, Ryan C. Gordon and the Humble Indie Bundle team.
Edit August 3th 2011 We updated both the Mac and Linux builds. Mac version should now finally work on the 10.5.8 and Linux version should now have fewer depencies. You can download the new version from our site or from Humble Bundle.
