Having recently finished Katawa Shoujo as well, I thought it was okay, but, considering my enthusiasm for it back during the demo stage, I was disappointed with the way most of the routes eventually played out. It's well enough written, but I would agree with Maxon - the story is mostly by the numbers, once you get past the unusual setting.
Saying that, I would not turn up my nose if someone actually produced the much joked about Kenji route, in which his insane theories turn out to be true, leaving you and him to battle against the global feminist conspiracy...
