Demo was awesome, I went back to get all the hidden collectables and loved every moment. I like how it's not too challenging unless you want to get all the lums to get a good score in the end, and then it becomes super challenging.

Reviews should be for the consumer. Strictly purchasing advice. Using a review that you know will get a lot of traffic as a soap box for what you think about broad topics of game design is sort of irresponsible, imo. Game design critiques are awesome and valuable, but they should be kept separate from the review.
Totally agree with the rest of this article though.
