You are Object 17. Someone unknown is forcing you to undergo mental ability tests. What happened to you? Where are you? Who is testing you? If your number is 17, then what happened to the previous 16 subjects? You will have to answer these and other questions during the game.
Collect puzzles from three-dimensional models of the famous Tetris. Move and rotate the figures as you like. The goal is to fit all the figures into a semi-transparent box in the center of the location. Some figures will be locked. To unlock them, you need to solve a problem.
You will have to use your abstract thinking to the fullest. Go through the tests on the flying islands in the open space of your subconscious. It won't be easy!
