I was watching a video of Easy Allies about Knack 2 (they trashed on Knack 1, have massive hype after playing Knack 2) and they actually said that it plays like god of war and it's the new god of war.
With god of war changing pretty heavily and looking at the gameplay of knack 2, it does show striking similarities to god of war (except co op and less blood)
Video starts at 1:00 more or less
Honestly Knack 2 looks like a huge improvement, though I haven't played Knack 1, but yeah, Knack 2 looks super cool and it's coming at a 40 dollar price tag to boot, the meme for Knack is Back is real and great but I think the meme is becoming real and Knack 2 will actually be a solid game, especially with a buddy in this generation of very few couch co opy games, especially in the AAA stage.
Full parry system, more focus on platforming, full co op where one isn't a shitty sidekick meh thing, hidden side stuff, apparently stuff like shrinking down to get into big things so you can control them, team techniques, dash dodges, super modes, etc etc, Knack 2 is going to be a great game, looks like we're getting 2 god of wars exclusive to ps4.
