It's very possible that A Boy and His Blob will get lost in the shuffle of late year releases, but it would be a shame for that to occur. It has an unpretentious and easy charm that's rare in games these days. It's both well designed and well presented, and it takes few missteps. From a control standpoint, there doesn't seem to be a reason that it only appears on the Wii, and perhaps a wider release would garner it more attention.
But it's very possible that more attention isn't the developer's goal. Rather, A Boy and His Blob seems likely to wind up in the hands of those that would enjoy it most by word of mouth if nothing else.
