This a thing of beauty!
Since the first one came out... I have checked the portal daily looking for this sequel (often doing nothing else on NG after not seeing it there). There is something, soo... gratifying (sp?, it doesnt look right...) about playing this. Its very tactille, and soothing. I love this. Easily the best physics game I have ever played (and I started 20 years ago with a Coleco).
I'm sorry for gushing, but I'm a fan of yours, and I love this.
Thank you.
