Déjà vu is Escape room game where you enter an old house and get locked inside. You must solve several puzzles to get out. When you unlock exit doors, you find another room which is same as your current (nor only one room but whole interrior) but something is always different (or at least puzzles are).
I want most of the puzzles (at least mechanical ones) to be working. That means I will be able to use 3D printer and build them myself.
