(I have this game through Steam, not GOG if that makes any difference) This game is just Silent Hill 2 mixed with Twin Peaks. I don't mean that in the sense that the tone feels like a mix between the two, I mean that it's almost exactly Silent Hill 2's storyline, but with scenes from Twin Peaks thrown in. It's even got it's own Red Room with a little dancing man, but the room is blue instead. An OK story can still be saved by good gameplay, but I felt like the gameplay was a bit of a slog. Sneaking doesn't feel tense on a 2D plane, and fighting enemies feels like a chore. Most enemies are your height, so you just point yourself in one of two directions and slowly fire straight ahead. As long as you don't fight too many monsters at once, you'll be fine. The game isn't really bad, it's just not very interesting or memorable. I'd recommend playing Silent Hill 2 or watching Twin Peaks instead of playing this rehash.
I don't understand how anyone is able to play this. If you use a mouse and keyboard, your character will fling themselves about the room at top speed. You can fix this by using a controller, but then your aiming reticle flings itself about instead. I've tried setting my character to always walking and lowered the stick sensitivity down to it's minimum, and at best that flings yourself about slightly less.
