Well, I would recommand not doing it in C2, as search engines will not be able to have the informations needed to rank your site well, and also you will also lack the "one link per important info" thing (unless you do it right with some clever manipulation of urls, that being useful when a people want to share a special part of the website)
Also, you used letterbox scale, right? I can understand a game being played under a certain aspect ratio, but a website? I was in portrait mode when I opened the link, more than 2/3 of the viewport was useless to me until I used the landscape mode again.
The links in the link sections were not working (perhaps there was no touch input setted up? You can insert the touch object to do this job, and I am sure people will help you if you have troubles with it)
And my last complain: the idea is not bad in itself, suspicious (most people will dislike having a 3rd party choosing for them what is safe and what is not, but really, if they dont like it, they can just not install it), but not bad per say, however, I am kind of doubtful about the efficienty of it, I mean just that a changelog saying "porn website added" is not that informative for people, but if you were saying more informations then your site would likely be just a list of porn websites for most people, going agaisnt the first goal of it. But if you add the list of ransomware and others, that would be nice.but now that I think about it, it is more a "safe browsing" for children so none of what I said really matters that much, but adding a little "we recommand you to keep an eye on what your child may be doing on internet, as this extension may not be bulletproof!" is I think an important thing to do.
