There is nothing more frustrating than having Moviestorm crash, the power go out, or accidentally press "don't save" when quitting, and finding that you've just lost everything you've been working on. It's happened to all of us. In fact, it probably happens to us more often than most, since we're frequently working with half-written code.
Well, those days will shortly be at an end, with the new autosave feature we're putting into the next release.
And it's controllable too... ain't that sweet?
