It's good, but it could definitely use a remake of sorts. The voice acting makes it nigh impossible to take the plot seriously, the animations, while good for the GoldSrc engine, are pretty janky. It looks good for the monsters, but not the humans.
Also, regarding the jumpscares. I'm not one of those "Jumpscare = bad gaem" people, but I do agree that the jumpscares in this game just come off as annoying and kill the mood. Especially since a few of them are much louder than the rest of the game for no reason.
