This was an interesting game.  At first is was not obvious what was going on; this is mostly because interacting with the books was easy...but not obvious what what happening.  A good example of this was for 'Shop', the purchases were spawning out of view (need to rotate to the left to see them).  Once realizing how the game works, the it was pretty neat to be able to place the objects around the room.   

It's definitely an interesting concept.  In the end, it seemed more about decorating the space than about work or shopping.

Some background music and sound effects when interacting with objects would bring it to life.  As an idea, background music can be added when the player 'buys' a music box at the 'shop', which you could make an early purchase option.

Funny I destroyed that wardrobe

Once I got the hang of it, it was a lot of fun.  Basically trashed my room though, which was funny.

Nice idea! We loved to decorate the room! Please consider adding audio effects / music as the game could really benefit from it :)
