Knack is $10 on PSN This Weekend, and It's Dark Souls for Kids
This may already be widely known, but Knack is a really hard game! This is a video of the second world from the game where I repeatedly get my ass handed to me.
The game got some lukewarm reviews when it came out back when the PS4 launched, and I would agree that it's not the most impressive game out there. However, you could do a lot worse for $10 if you missed this game last year.
