First of all, I think you did a really good job with the music. It has a lot of charm to it, and adds a lot to the atmosphere. It's a little detail, but i liked the button animations a lot. Overall, you did a great job at making sure the different parts of the game added to the atmosphere of the game, things like the way the voice sounded made it feel more dark and serious.
A thing i would have liked to have seen however, because it's important to be able to understand what the voice was saying as well as the fact that it's an artificial voice, and just a good idea in general for games with dialogue, would be subtitles. it would also make the game possible to be played by people who are hard of hearing.
Great Job!
