After seeing the gameplay (of this one level) I agree that it looks somewhat bland and bare-bones. It seems like you're just running through an empty city... there aren't even that many enemies to fight.
I could also tell that Knack himself seems to run kind of awkwardly. Not very fluid, in my opinion.
However, I still think that this game is really interesting, one of the games I actually remembered from the PS4 Reveal. Maybe they could work some kinks out in the final stages of development? (If that hasn't already passed, which it probably has.)
