I believe this will eventually be a press release, but it isn't quite yet. I cannot reveal my source, but I have been allowed to share it with you. This is Ed McMillen, developer of Binding of Isaac:
Ed MCmillen said:So as you may know, The Binding of Isaac was released on Steam last week, and i have to say I've been very taken aback by the overwhelmingly positive and high review scores, even more so by the sales numbers that now rival Super Meat Boys release numbers. I never at all expected such a great launch and die hard fan base, especially for a game as odd as Isaac. As I've mentioned on my blog, since the game has superseded my expectations, i will be doing my best to give back to the fan base that got me where I a today and continue to support my work, much like we did with SMB.
First off, i just released the "Flash Demo" of Isaac on Newgrounds.com (http://www.newgrounds.com/portal/view/581168)
The Demo consists of 2 of the games early levels along with 8 possible bosses and 60+ items, enough to get your feet wet and i believe it gives a good sense of what the full game has to offer.
Second i'd like to officially announce that The Binding of Isaac will be getting a very large (and free) content update via Steam this Halloween.
The update will consist of 20+ new items, 3 new bosses, 1 new playable character, a few more achievements and a new "final chapter" for the people out there who have "finished" the game.
This final chapter should be a much bigger challenge.
This 2nd update is more or less my dream update, something i wanted to be able to do for release but knew it would push the game back another month to get done, so in a way on the 31st Isaac will become exactly what i wanted to release but didn't have the time to finish.
One of the many awesome things about steam is the ease of updating, so this should be a very seamless update for people.
