The game has its unique art style which creates interesting experience. Unfortunately, all the puzzles are extremely easy to solve, but the executuin of the solution is sometimes tedious and sometimes hard becuase of very clunky controls.
I would give it 3.5/5. The presentation is ok. The background looks promising and interesting, but you quickly find out it is there only to look at from the distance. You are confined to a fairly limited premises of the puzzle at hand or occasional sculpted story snapshot. Nevertheless, it sets the mood nicely. The "story" is presented by a sequence of unmoving sceenes without any direct commentary and is pretty generic, without much detail and specifics to be really called a story. After solving optional challeneges, the player is presented with scrolls containing deep and wise sounding out of context trivialities of questionable merit. Among them, some conjectures presenting conspiracy theorist worldview are interspersed, which is also the impression of the "story". For this I take down one star, because it is really off-putting. The game itself is quite good. It is a bit on the easier side, but some good challenges are wainting in later stages. Some reviewers complain it is repetitive, wanting some new meachanic every other level. I feel like every level presents some new interaction between the mechanics already known. Maybe not always that interesting, but I did not feel I am solving a level already solved. The levels are easy, because they are usually quite limited with only a few objects and paths to interact with, so you usually quickly deplete all possibilities but the right one. I think using isometric or some other global view would allow for some bigger and more complicated puzzles. Also, in the first person view you are much more aware of your immediate limits, which makes it feel easier. Unfortunately, the toughest challenges for me were not tough for the right reasons. They were tough because I had to poise on an edge to be able to make seemingly impossible visual connection or because I had to move quickly and try to cut corners through some tightly timed section. For this I would drop the 0.5 star.
After finishing it, I have many contradictory feelings about htis game. Overall, I enjoyed it very much. On the other hand, any aspect of it I choose I see some problems. The game starts and most of the time feels like walking simulator. You roam deserted stations and uncover the backstory by watching, listening and reading what you find. You progress by doing the only obvious action there is to do. The game has very few puzzles deserving to be called that. I'd say maybe three, none challenging. This gameplay is regularly interrupted by arcade sequences where you are usually timelimited by lack of oxygen and need to get to safety. The setting is quite immersive and looks believable. No shiny megalomaniac structures. Scratched screens, failing systems, place where you can see yourself working and living. Regrettably, some places are very strangely designed (eg. when the only way from the control room to fuel storage is through auditorium). One strange quirk I noticed is that the moon's small gravity applies only when in vacuum. Whenever inside, the gravity is Earthlike. It might be simulated by magnets, but it does not seem there's always some metal underneath inside, while there sometimes is outside. The story is some sort of sci-fi thriller. Unfortunately, after every step of the story I had to ask "why" and never got an answer. There are obvious more accessible sources of energy than the moon. The main "bad guy" uses unnecessary scorched earth approach while obviously having idealistic non-aggressive motives. Safety and operation procedures seem to be designed by "If we have a problem let's make it a big mess" rule. I don't have problem with the combination of walking simulator and arcade gameplay because I like both types of games and the arcade sequences are organically placed. I can forgive the absurdly small oxygen reserve that makes these sequences possible. One star I remove because of the story holes (I would remove 1.5 if it was possible).
