SOMA's main problem is definitely the fact, that every monster encounter boils down to sneaking and hiding in a corner (occasionally running away when you're spotted), it's a real slog. There are some underlying mechanics, like the way some creatures react to noise and your flashlight or shouldn't be looked at directly in one instance, but in the end it always plays out the same. I guess I would've preferred more emphasis put on figuring out these mechanics and making it more of a puzzle. It is also quite disappointing to realize that the game basically repeats the same three section over and over again. You stumble into a new station and get some time to explore, a certain trigger activates spooky mode with one or two monsters looming around in the area now and finally you get a break with some dialogue in between afterwards. That's pretty much as far as my complaints go though, everything else is top notch, the story and themes being the most noteworthy.
