Wait what, Gurumin is coming out on 3DS???
Literally one of my favourite games of all time, Gurumin is amazing. It's Zelda-like with more classic JRPG style dungeon adventuring and platforming elements, with great anime styled character design all wrapped up in a beautifully cute art style. The music is also really good.
Basically you should definitely buy it because it is amazing, and so should everyone else. I will be buying it!
