When sifting through the demos in the Nintendo eShop, I came across this adorable little platformer called Mutant Mudds. From the screenshots shown in this post, you can see that it has a sorta; cute retro feel about it. It's a generic platform game, no doubt about it, but the way it's played and how the controls are designed and handled; you could say, Mutant Mudds was built perfectly for the 3DS.
