Swing Swing Submarine’s new game, Blocks That Matter, has a tech demo out for the upcoming non-XBLIG version. The team is asking for feedback and debugging help, so be the kind soul you are give it a try. The demo should run on Windows, MAC, and Linux. You can download and give the demo a try here and report bugs at contact@swingswingsubmarine.com

Please note that there are other mirrors to the demo. So if the first link doesn’t work, try the other two. Don’t be like me and feel sad when the first link doesn’t work and not realize there are others.
