Spoilers for the game. I would recommend playing the game beforehand, it's short and pretty good.
First off, I really love the aesthetic of the game. The lidar mechanic feels like a perfect balance between being able to see your surroundings and feeling utterly blind, if that makes any sense. As far as horror goes, I feel it pretty much disappears when you realize the monster can only appear when you use the detail scan, but the first time really got me (and the "blast shadow" it left behind was a really cool effect). On a similar note, the ending is a bit underwhelming (it even made me chuckle a little). All-in-all, though, I'm glad I gave the game a spin and didn't just watch a lets-play and leave it at that.
PS: There's a ledge in the second level that can easily be traversed to get out of bounds (Well, there are two, but the second one is harder to get to and won't get you stuck). It's pretty fun to explore out of bounds, but you'll get soft-locked if you fall off a ledge while back there.
