Knack is a game with some solid core mechanics which cry out for a bit more polish and a lot more variety in the gameplay. While changing size is truly amazing, it doesn't bring enough in the table to make the lengthy game fun, and it becomes quite tired after the halfway mark.

Knack is not only a miserably boring action game, but it features one of the worst heroes ever made. Knack is easy to kill, stupid looking and part of an adventure that will never end. This PlayStation 4 game is too difficult for kids and too generic for adults. It's a disappointing failure on just about every level.

A pretty good game for those looking for a platformer with melee combat. Although it's presented very well, the game is held back by its linear design, repetition and lack of replay value.

Provides PS4 owners with a solid if unspectacular adventure and a decent dose of family friendly co-op gameplay. Give it a try.

The colourful visuals can't save Knack from its absolutely tiresome gameplay.
