The game does a fantastic job of telling you absolutely nothing. The launch sequence is frustrating as hell. You're shown a diagram near the beginning of the game that looks very little like the actual control panel. Imagine a child's drawing of a house compared to an actual house.
Once you fumble through that 10 step process (which must follow a specific rhythm and pattern, mind you), you are sent into space to dock with the station on the moon.
That part wasn't so difficult. At least, I didn't die. From there you have to restore power, and therefore oxygen, to the lunar station before your personal supply depletes. Please tell me who carries 3 minutes of oxygen on their back for a space mission.
The lunar station is unmapped and hard to navigate, especially as you're floating almost uncontrollably down (or is it up) the many branching corridors. It's difficult to get turned around. The hints are vague. The random oxygen containers you find as you're flailing through the lunar station are sparse, and they don't give you much. Maybe 30 seconds apiece.
Expect to fail repeatedly because the instructions and guidance are nonexistent.
If you can get past the awkward controls and the poor object interaction, the story is in fact very good. However, there are plenty of other things in this world that I can get frustrated at without having to pay $20. If I wanted that, I can just go to Walmart and watch people park badly. Or watch the news. Plenty of things to yell at on the news for free.
