Everyone gets sad sometimes. Maybe it's a dreary day outside, maybe you had a rough day at work or maybe even -- knock on wood -- your significant other broke up with you. During those dark times, it's nice to know that games like LocoRoco 2 exist. After getting some hands-on time with the PSP sequel, IGN has postulated that no one can remain unhappy when playing this game. It is physically impossible. Because watching a bunch of cute singing blobs bounce around a cheery, colorful world is just too damn adorable.
