Beautiful graphics, creepy monsters, fun crossbow mechanic, excellent voice acting, witty script and interesting story. Definitely worth a download, even if this isn't your genre. The difficulty may turn you off eventually, though. It's difficult to tell where some monsters are going to fire or swing, and your dodge animation is pretty slow; eventually you'll read the tells, but it's not easy. Dodging feels a little unwieldy, and is unfortunately a requirement to do serious damage, landing "hits" instead of "grazes" (so you can't sit there and eat damage whilst hacking away). Regardless of the tricky and punishing combat, it's worth it to continue the story and hear what the witty, crazy(?), wheelchair-bound gentleman over the intercom has to tell you next.
This deserves special notice, because this is apparently the guy's first time at professional voice acting. He reminds me of Zoltun Kulle from Diablo 3, and he always says something new. That is a lot of voice acting to stay fresh, and it's all marvelously executed. I couldn't find the name of the guy, but if you're reading this, keep it up!
Five star-worthy on graphics, sound, story, and voice acting. 4.5 stars for combat.
