I just got the game today (3/8/15), but sadly I had to get it digital for 3ds AND Wii U. Currently I'm on 5-4, but I won't spoil the names 
So far, I love the game, and this series can really help your puzzle skills! I haven't played the Level Editor; I'll save that up until I play each main level with a gold crown. I really can't wait to see what happens next! ;D Also, if you have never played the series; I highly recommend you get it. It's tons of fun! And besides, it's only $19.99 in US money! Are you guys getting it (if you don't live in the US)? If you do have it, how far in the game are you and how are you enjoying it?
