This one seems to be slipping under the radar and I don't know if its a real launch title or not, but I've been seeing some ads containing the game for launch day. It seems like it could be a decent puzzle/action game and while there are other games I'd rather buy first, I was wondering if it was a good enough purchase for something down the road. Have any of the pre-launch reviewers who've already gotten their PSPs + review copy games been able to give this one a spin?
