A very delightful puzzle game, that lasts 3-4 hours. It is not going to kill your brain, since the avarage difficulty of the puzzle is on the easy side. Most of the time they just require you to explore a bit the surrounding and have a few try to understand the right perspective "trick" to solve them. Everything is connected by a nice narrative based on the main theme of Superliminal: as you need to use unsual perspectives to solve the puzzle, so you can to face your problem. I felt the influence of games like Portal is strong, but neither the puzzles or the narrative is near that level. Still it's a nice experience and it entertains for its duration.
