Neat little app?? – Planner 5D: Room, House Design Review

I had this app about 2 years ago and it was so fun to use. I played around with it even though most people use it for work. I never had the premium version but I considered it still fun to use. Now That I got my new iPad all figured out and stuff I’m thinking about getting it back on here. Can someone tell me how to add a 2 floor without the rooms and floors becoming identical to the first one? I struggled with getting right, so the items wouldn’t sink to the other floor. Sorry, I know it’s confusing and I wrote a long review because I finally found it again. Thanks for the help!!???????
