Hope this is not too TLDR.
I think one of the key reasons she thinks it's a dating sim is that a New Girl pops up right away. And not just one but two--Allison and Olivia. It's possible she just hit an ending with nobody to go to the fair with and figured, well, that's it. I played Mr Nice Guy and got the Tina ending first. Now, if you don't hint the possibilities after a bad end, that is something you can probably tweak pretty easily, since you have a solid grasp on your game-world.
Incidentally, I also have some reviews up at http://drdanstreetmentioner.blogspot.com.
There's a lot of criticism I didn't elucidate as well as I'd like, but I want to at least take another stab through and note low-level stuff like typos etc. because you guys clearly put work into it and you deserve it. Plus I'm good at that sort of thing--I tend to work bottom-up before noticing, hey, this is how things fit together, and then I'm able to find stuff more subjective. I really don't like reviews that nitpick and do little else, but all the same, nitpicks are good to notice to help the author polish things, and if someone's finding nitpicks, it helps the author think bigger. Also, an area with a lot of grammar/small style errors may have bigger errors that are tougher to figure.
And yeah. The "old ones" can sometimes seem a bit insular. You can read examples of their old reviews to see what they can expect. They include generally people with high level degrees from elite colleges, and these people have assumptions and expectations. Some of that may not be fair, but some of that may help people here consider stuff they wouldn't anyway.
I have to say, though, I entered last year and got two reviews total, one being a day before the contest ended. So as long as the reviews aren't abusive, I hope there's something there.
Also, if people are willing to hose players' save states, I think updates are a very good idea--it shows judges/players you're committed to making things better. It doesn't have to be a ton, necessarily. A post-comp update is definitely worth it. (Heck, I'm still updating my last year's game. It needed it. It probably still does.)
As for games being tough or fair or not--how many people have looked at the Players' Bill of Rights? An (updated) example is here. I refer to it when testing friends' games.

As for what to update, a good introduction and well-checked walkthrough can go a long way.
And as for the Hexagon game review, I'm pretty impressed someone blind (and 17) is writing anything at all. And I think he deserves encouragement for doing better than his first two games. No, I don't think it's as good as any of the three CYS games. But it offers something different and unusual and if it's a bit too random, well, it shows some imagination.
I also agree Bear Creek is quite entertaining, and I think it paces itself well. I'm not sure I want to comment on the other games yet, since I helped test them.
