If you've played other games from the Gotmail team, then this one may seem familiar to you, but it really is a new game. It may appear familiar at first glance because Bon Voyage uses the same art assets and setting as Gotmail's previous game, Strawberry Tomato. In fact, some remnants of the previous game — such as the small pictures on the wall that contained clues from the previous game — are still there, but they don't respond to mouse clicks.
Use the usual point-and-click skills to locate clues and find items to help you escape. Some pixel hunting will likely be necessary as well. Fortunately, the game includes an integrated save mechanism and a music mute button. Go forth and conquer, and leave some helpful hints, tips and a walkthrough here in the comments if you can. And if someone can come up with a better review, I'll edit what I have here to include that, too.
