Ummm, I don't see any subtitles in that video, although I am sure that the PC version does have a subtitle option. Hopefully, they were not removed for the iPad version of the game, and possibly the reason for the lack of them in this video is that the poster was playing the game with them turned off. The video looks good, otherwise.
I have read some reviews of the PC version, and have heard that the game is very short, much more so than any of the previous Dracula games. The file size is huge, though.
I will wait to hear if anyone can confirm if subtitles are available, and probably for a sale, based on the short game play.
