This game is simply ground breaking. There is quite literally nothing 3D with this good of controls, animation, quality. This feels like a game made by a small studio, not an NSFW game. 

The way this game is actually capable of psychological horror. It's surprising how a game with one single enemy to shoot at manages to have me on the edge of my seat.  

The puzzles are pretty well designed, though there is two bad puzzles. The gray section of a window you're supposed to know you can shoot that drove me crazy for an hour searching around. And one of the last puzzles in the game that involves you running across a gauntlet of electrical machinery is just awful.  

The plotline is amazing. It feels a bit like "dead space meets the passenger." And believe me when I say that I can easily compare this to dead space. 

The game is not without it's flaws. Having only one enemy type does eventually get disappointing. Even with the well done psychological horror, enemies that jump out at you from corners, only having one enemy type does get stale and I stopped being afraid at a certain point. You can't just blue ball the player going "this time there's gonna be a huge monster waiting for you on the other side" and there's nothing.

Overall, this game will take you between 3-6 hours depending on how good you are at these types of games. I'm not very good and it took me around 6 but you can get through it way faster. I cannot recommend it enough and can't wait to see this game's development.
