I played the game, and it's not the crummiest thing alive. Okay, that was harsh but there is a point towards that...
This is probably a mini-game you just made quickly, considering the map style, lack of more levels, and no story or opening scene to boot. That's not a bad thing, this is an event system anyway, so I don't need to criticize on that area. However, your Lost game is simply a maze game, trying to find the exit from a starting point.
I do not like the mapping here, all it is are jail cells. Plain old jail cells slopped over each other with no sense of love and care. Maze games are hard to deal with, but they can be utilized awesomely (Or look beautiful) if you give the correct walls.
I'm not going to comment on the music, since I'm in a noisy area where I can't easily listen to it.

To make this game more original, you should try adding some interesting things...really interesting. :3 I like maze games, though there's something funny about this one. Maybe a laughable one, or a strange kind, but nonetheless.
