I'm hearing that Renegade Kid's unapologetically retro platformer Mutant Mudds has breached the last defensive line and should be invading the eShop some time in February, if all goes according to plan. Nintendo isn't exactly one to break a volley once it has a streak going, after all. Cross your fingers.
In the meantime, a small collection of 3D images have been posted up on the Renegade Kid site. All you have to do is visit this page on your 3DS and click on the screenshot you want to view. The 3D effect is very subtle, a lot more easy on the eyes than the effect in other games, I think. Go give 'em a look-see!
