At the time when I only had a 3ds it worked, sure it only updated to 1.9 and only has a small map but it's fun. I personally did not experience lag or any glitches, even after I built a giant statue of Sonic, it ran fine. And beating the game felt a bit easier than Java, and Redstone is a bit different in this version. If you only have a 3ds, play it, but if you have a pc. JUST GET JAVA!
