Loved the idea, and really liked the game. The only thing I think you could've done better is to be more clear on what the end goal is. It took me some time to understand that the messages where clues, and most people will not figure it out. So even one little nudge on the right direction at the beginning of the game would do a lot for it.

Or a little more feedback on what was wrong when chosing the wrong door.

Very nice looking game, and intriguing as well, but is it unfinished? it says sorry and than restarts the level :(
