I played Dark Fall: Lost Souls for about 4 hours, although letting it open while I was AFK caused Steam to think I had about 56 hours of gameplay. I absolutely love horror graphic adventures and I can objectively say this game is terrible.
The gameplay is very tedious, walking and turning around are slow actions, and you get stuck in the game without any signs of what you should do next very often, which wouldn't be so bad if it didn't take you years to go from point A to point B and explore it. Textures and animations lack details and make the game look older than it really is. The overall atmosphere is pretty good, but in the end the only really scary parts are just cheap scare jumps (really cheap, literally just an image appearing and the music going loud for a second).
The story reuses a lot of elements from Dark Fall: The Journal, and it's not bad, although the endings are incredibly disappointing (there are two, they only depend on a line in the final dialogue).
The worst thing about this game is the voice acting. It is AWFUL, most of the time lacking emotion or, on the contrary, sounding too forced. It kind of reminded me to the voice acting in Resident Evil 1, but I would choose RE1's any time.
I bought this game 75% off and I would undo it. I wouldn't even try it if it was free. Really, it is THAT bad.
