Finished it. Was a nice little experience and I liked how the companion app 'helped' me on some situations.
I do wish it would have been creepier in some way. There were a handful or 3 fingers full of jump scares but the rest was just kinda 'eh' in the scary department. Patrick talked it up big on the bombcast so I guess that's why I was expecting mind numbing terror.
Still, I had a decent time and will be recommending it to my friends. Glad my 3GS ran it with no problems.
