Growing and shrinking is entertaining, but the player never has a choice. Absorbing materials into Knack’s body is intriguing, and yet, it’s only ever done restrictively. The bareback approach to combat is something fresh and interesting, but after the game forces you to take part over and over again, it becomes stale. The concept of Knack is such a fantastic idea, and if they were to make a sequel with any kind of player choice in regards to absorbing materials, growing, and shrinking, I would likely be keen to play it. As it is though, Knack is just an adequate game that might be worth your attention if you’re just looking for something to kill time with on your PS4. If you come in with low expectations as I did, it may actually surprise you."
