Sorry it took me so long to reply...Loved HCF, it's very atmospheric, and very different (I'm always on the lookout for more original games) The moment when you find out what exactly you're doing is pretty jarring, and delightfully unexpected. As for what HCF means...I'm still working on it. I'll follow you on Twitter and let you know when I've figured it out, lol. And thank you so much for the positive comment on the quick little game I made; seeing that email pop up was...well, I needed it that day :)
