Thank you for the kind words.
First, the grainy look I am assuming is coming from the walls and fencing sections. Don't worry, those have been changed for the v1.0 release. The res has been bumped up and a whole new fencing scheme is in place.
Second, Since the fence has been changed, I hope it meets with approval from all the people (and I am still shocked at how many of you there are) who have downloaded and played it.
