I enjoyed the story! I would have liked a little bit of art to go along with it, even if it were just still images like your cover picture. But you were able to do so much without any art that I have to say it is very well done. The sound effects and music were GREAT. They made it feel immersive and interactive. That was my favorite aspect of this game.
I was a little confused what was happening to the people and would have liked a little explanation on that. When the princess started to go crazy, I was confused. And why did traveling make her fine again? Maybe I'm dense, but I also didn't connect why the songs were the solution to getting home. You could add a little more exposition about that for people like me that don't connect the dots automatically. :)
Overall, really well done.
