not bad
I personally hate zombie movies. I think that the rise in popularity is cheap writing, requiring a bunch of extras in destroyed clothing and makeup. Also, I've had more than enough bad dreams about zombies, that it ruined the genre. Shawn of the Dead is the exception. This game is a lot more fun than most zombie games, because it uses a point and click escape means of play. I'm tired of this so I voted 2 - nothing too new or interesting, but I'm giving you a seven, because you at least took a couple of otherwise tired genres and put them together nicely with real life photos, rather than bad drawings, or something similar. Also, it wasn't just a shooting game, like every other zombie game out there.
The take on the Raven was interesting, and using the meter and style of it was cute. Poe is a generally fun author, and I'm glad that you could put some elements of his most famous poem into this game. Good literature in games isn't always great, but if done well, it leaves a satisfying impression. All in all, a good effort, and I would love to see more like this where you aren't just clicking around, and you don't need a walkthrough to win, and it takes you on an adventure, rather than just having you escape a room or something.
