hey everyone, on monday I finally got a happy home designer of my own! other than the obvious of planning interior/exterior of buildings is there anything else i should know or is there anything else to the game? thanks so much
As you play enough (i.e design enough homes/public facilities) you should unlock the laptop on Lottie's desk! There you can connect to the Happy Home Network and see other people's designs. You can also enter the monthly challenges to obtain special items/furniture!
Also you can get DLC content for HHD which is essentially getting special design requests from special characters. You can obtain special items/furniture from these characters. These are from either the Nintendo Zone or Spotpass and you can check them upstairs on the blue 3DS. (Not sure when you unlock this though, sorry!)
