The game is fairly short, I finished it at around 6 hours but it felt much longer than that as the game was a slog. The core controls for your camera movement are painfully slow. All the "puzzles" are self evident, no thought required actions that feel more like busy work than a test of your intellect. The only challenge I encountered were the controls themselves, it not always being clear how you are supposed to input something, or get to a certain screen. The control scheme having random button choices and many unnecessary button holds instead of just pressing a different key felt uncomfortable and felt like a bad pc port of a console game. While the game environments look nice, the game stutters a lot, and character facial animations look off, not always syncing with dialogue. There was a point where an object unintentionally clipped through the camera during what should have been a tense moment. The atmosphere, sound design, and general mood of the game are nice, but the poor controls and dull game-play sour the experience. I won't spoil the plot, but suffice to say Observations brings nothing new to the table as far as sci-fi horror goes. A Space Odyssey this is NOT. This would have been much better as a short film instead of a game with poor controls, if you are still interested, go look up a play-through online and watch that instead.
