Really good game! three things I would want to see if you were to keep working on this:
1. More decorations and room layouts. you can never have enough!
2. More rotation options. I wanted to put some items in certain places like the TV, but because of the limited rotation options the screen would always be facing away from the bed or at the wall.
3. A way to save an image of your room and export it to your computer. I think people would love that!
you've got a real winner on your hands!
