This is an audio-visual delicacy, and inarguably one of the most creative entries I seen so far. The implementation of the ideas and communicating the key aspects of the game towards the player was a difficult task, and even though the narrator and the poiting arrows helped a lot, I agree with the other commenters that there is still plenty of room for improvement. Actually, without the comments, I would end up giving up way too early.
Anyway, bold ideas and a willingness to innovate is always admirable, especially if it's done in a visually appealing way, so, well done.
