I received my confirmation email this morning, my entry has been accepted for the 2008 IGF competition.
I'm hoping that Crashblock will at least make it though to the finals, although from what I've heard, even getting that far will be a major accomplishment.

According to the email, I can update the game at any time, the judges will take the most recent version.

Crashblock is available in Beta test, so any issues which are reported will be fixed and applied to the IGF version too.

I'm up against stiff competition
