I was starting to work on this project last year when I had my car accident. Because of things that were going on, I lost track of it for a couple of weeks, and basically by the time I got my bearings, the guy who was running Sandbox Games seemed to disappear. The webpage disappeared a month or two later and was replaced by a different page about an "independent game studio" that wasn't doing anything. It hasn't been updated in six months.
Maybe something is going on behind the scenes that I missed, but in general I think this project is dead as a doornail, sorry to say it. Personally, I'm too busy with my real job and Allacrost to do any other programming work.
So, I don't think this forum is going to be serving much purpose. Just an FYI.
