I just got done playing the demo of 999 which you can find here. I enjoyed solving the little puzzle the demo presents and I"m interested in seeing more of the game now. You should definitely check out the demo and say what you think about it.  The puzzle in the demo seemed somewhat simple, but  they could probably get a lot more complex in the final game. I might just have to check this game out.

I had no idea 999 was an escape-the-room game. I kept on seeing it mentioned on Aksys' page, but never read too much about it. (Too busy to see if they were going to re-release the petits of Noel) 
 
After playing the demo, I am very much looking forward to this game. I've always been a fan of escape-the-room games, ever since the first time I played and solved the Crimson Room, and the episodes that followed it. 
 
Thanks for showing me this! Escape-the-room sounds perfect for a DS title. It shall be added to my wishlist of games.

So if i dont escape the room what happens?

I just bought this game on a whim. I love the Hotel Dusk game for the DS, and thought this looked like a  similar style of game play. Did you ever pick up the entire game?
