It's scandalous that there isn't a thread for this delightful PS3 Network game. There's a demo out now and the full version will be out on July 31st for 10 bucks. I really enjoyed the demo, day one purchase for me.
Here's a bit from a nice interview ripten did.
Patrick: How would you classify Pixeljunk Eden? Is it a relaxing casual game, a challenging hardcore game, or a combination of both?
Dylan: PixelJunk Eden is a relaxing game which is challenging at the same time. I think we’ve somehow magically struck the perfect balance, but that of course is up to you all to decide.
Remember that Mario Bros. 1 was a “casual” game that probably billions of people have played and enjoyed, but at the same time it was incredibly challenging, but because of the amazing attention to detail in the controls for that game you can still play it now and have a ton of fun. This is what we’ve aimed for with Eden’s core dynamics. We think people will play this game over and over again, simply because it feels fun all the time. I’ve probably played it the most and I still boot up a different level each day and have a blast. There’s just something intrinsically “feel-good” about it.
