Knack is quite a basic game but that doesn't stop it from being enjoyable. You play as a living relic who constantly changes in size to increase his strength to progress through levels and fight goblins and robots. The gameplay while quite simple is fun and full of cool characters and cool creatures to fight. The checkpoints can get quite repetitive in some places other than that I cant fault the game. Great for the kids (which in my opinion there is not enough light hearted games for kids to play recently).
