Nice art! The atmosphere is amazing. My only problem with the game is that I die too much (and I don't think I could've done anything about that) and, with duration of the death animation, waiting gets annoying. I also don't know if it's a bug, but somehow after dying I could still move and shoot my camera. It's a great concept though, and with a bit of polishing and bug fixing, I think it would be a great experience!
