Neat little narrative. :) It took a while for me to get off of some of the invisible walls, but I eventually got through. It was a good idea to use echo/reverb for the voice over, to give it a more ethereal sound.
Thanks a lot. I think that narrative is a really good way to make more engaging type games. The invisible walls may cause a little problem, but the game is definitely worth giving a try and I hope you liked the message about parallel worlds and reality :D
