Agony

I played up to the second mirror, then I watched the rest at 2x speed in youtube. This game has high quality art and environment. It reaches the same level of doom by Bethesda or the hell seen in Diablo series. I dropped it because it doesn't offer that much value. It has some cool concepts, but it becomes a sore with excessive trial and error.

Limbo is trial and error, but because it's a puzzle game you always return to the same scene and every time you die you get closer to passing through that puzzle. On the other hand, Agony is made such a way that the player is forced to die to possess some body to get through. The puzzle to find the sigil to unlock the path is pure trial and error. There are no clues. The parts where you possess a demon is the same concept of driving a car in Alone in the Dark or Alan Wake. Its only purpose is to move from point A to point B.

It seems that they've used automated collision on a per poly basis or something because the player gets stuck in multiple spots. The geometry in this game is high density and maybe the invisible collision mesh is high density too? I don't know.

Somehow this game seems to take inspiration from Duke Nukem and Prey 2006. The first because there is sex everywhere in this game. The second because they've used the same mechanic of walking on walls from that game. Also, the doors that are shaped like mouths with teethes.

If I compare Agony to Amnesia. The latter is clearly better at conveying terror and tension.
