The upcoming puzzler Roogoo from Spidermonk Entertainment has just been previewed by Hilary Goldstein over at IGN Xbox. Roogoo seems to be quite an odd little puzzle game - having different shapes come down and requiring the player to match them up - like one of these but far more elaborate and difficult.

Interesting concept - one of the cool additions on top of this is that you can play 4 player Coop Locally and online, trying to solve each puzzle together! This might be the girlfriend game you've been looking for!

Co-op is a little more interesting. Either on a single screen or on Xbox Live, up to four players can attempt to pass the levels together. Players alternate between the platforms they control, with their avatar appearing when it is their turn. It can be a little confusing for the first few seconds, but quickly becomes second nature. You get a sense of when it will be your turn. Though each player is working together, there is still a competitive aspect as all are trying to earn the highest score.
