A puzzle game where the puzzles' goal are to reach the tetromino at the end. They have buttons, cubes, lasers and force fields similar to what you would find in Portal, as well as mechanics that interact with them (jammers, connectors). The game also has a philosophical story and backstory with optional lore terminals. The game is also divided into three worlds (and the Tower), each world into several levels, and each level into several puzzle rooms.
Ranked in these QuestionsQuestion Ranking
Pro Great storyline
The puzzles in the game are great, but they're tied together with a thought provoking story line filled with mystery and intrigue. A story about a robot with human consciousness who is being guided by a disembodied voice, are they to be trusted? As the story progresses the player is drip fed clues which can lead them closer to the truth.
Pro Difficulty ramp-up
Starts out easy enough, but gets to some truly difficult puzzles by the end. If you get stuck on a puzzle you can skip it and come back to it later.
Con Ending troubles
After getting the "normal" ending you will have to replay the entire game again if you want to find everything you missed. Replaying a puzzle game isn't that fun when you already know the puzzles.
