One rule: turn it until it fits
Swipe left or right anywhere on the screen to rotate the piece, smoothly, to the exact angle you want. Soft parts squeeze: watch the sofa cushions compress as they rub the door frame... just enough. Hard parts never bend: wood, metal, glass and stone need the right angle. The door frame turns red where it rubs, so you always see what is wrong. Too tight? The piece gets stuck, backs up a little and you adjust. No game over, no timer on screen.
