During the game,
Knack also discovers that he has a skill (in other words, a
knack!) that allows him to incorporate ice, metal and other substances into his body, giving him new abilities from level to level. The result is gameplay which is a little bit like
Crash Bandicoot, and a little bit like
Katamari Damacy, in that the
Knack can get quite large indeed. There’s also a touch of
God of War in there, in that there is an epic feel to the game in places.
