I was looking the coming soon games list for DS recently and stumbled upon this title. I've read about it before and it looks pretty interesting. This is a brief summary of what to expect from this title:


Gamefly's description:
Nine people are locked behind nine doors, and you have nine hours to save them in this breathtaking interactive mystery. Junpei is a normal college student who wakes up to find himself trapped in a deadly game. Kidnapped along with eight others, he has only nine hours to save the strangers and himself from a watery grave. Explore different environments and solve puzzles based on logic, music composition, numerology, and more to open the nine doors and cheat death. The story will take you into the darkest depths of human relationships, where one wrong choice could result in the loss of someone you're trying desperately to save.
If you're interested in looking into this game it comes out 11/20/10. I'm looking forward to playing it myself as I like action, adventure, and puzzle games.
