Bit-Tech published a review of Roogoo for the PC
Just because the game is tough though, isn't to say that RooGoo isn't fun. It is fun to play, kind of. Fun in the same kind of way as //Peggle or //Drug Wars or any other casual game. You don't actually massively enjoy playing the game, you just crave the sense of accomplishment and completion and you get sucked into this trap early on thanks to the pick-up-and-play design.Roogoo (PC) Review
There are only two real things that prevent / /RooGoo from being a good game and neither of these are really going to be a huge problem to any initiated puzzle fans. The first is that there really isn't much to be had beyond the single game mode and once you've played one level you've played them all.
The other problem is the way the game presents itself. We've joked about the bright colours, MeeMoos, King Goos, and Roos of / /RooGoo, but the reality is that they really are a problem. //RooGoo is too fast and frantic to be a kids game, so we have to judge it as more than that and while the game would still have problems if it was presented as a less immature puzzler, it would be a bit better off.
