I think, for a prototype, this game is good. The only downside I have with this game is "playing" it - maybe I'm missed something. But I didn't get any hints on a possible solution. It seems "random" to me. Therefore I was just clicking an answer which "couldv'e made sense to me" - being wrong awards you with a very long downtime in which you can do absolutely nothing. What I would suggest is, instead of a timer make the player solve simple tasks (memory, mazes, and so on) for being wrong.
There is a lot of potential even with the notes (which to this point are kind of "useless"). I can imagine, once you have more Tasks, more Glyphs to translate, it can be one hell of a puzzle game!
Music is great too! Keep it up! :)
