You need to either buy/steal/rent Locoroco. If you ever feel blue and you need some cheer up, you'll be glad to play this beautiful game. I never ever played a game that made me feel that way.
Great game, and a nice change of pace from the games that are all kill-kill.
You bet! Some might say it's too cute for its own good, but everything makes sense. You can hear the scare the Locoroco go thru when they go near the bad stuff, and you feel compelled to help them.
