Unsolved Mystery Club takes on a fairly standard point-and-click adventure feel. The scenes you are trekking through are static images with a few animated parts here and there to make sure the location has just enough motion to keep things interesting. The locations themselves cover a wide range of locations that will take the player from the Egyptian desert to a South American rain forest and even Antarctica, and for the most part, the artwork, while not photo-realistic, looks really good and clean.
The game's music takes on a few different flavors depending on your current location. One site might use flute instruments heavier than another in order to give a more exotic feel, while a different location might have some heavier drums to give off a more tribal vibe. While not essential to the game, the sound does a lot to pull off its ambiance.
