Alright, time for another round of me shitting on a game I've never played.
Spookys Jumpscare Mansion is not a good horror game. Now, there are several asterisks to this. First of all, I am only talking about the base game. Endless Mode is really challenging and stressful. Karamari Hospital... well, it shares a lot of the same problem as the base game, but the visual design is really unnerving, and Hanged Man is pretty cool. Doll House poses a decent gameplay challenge, with one of the most genius moments in any game that is so good I won't even spoil it along with everything else. Second of all, I am only critiquing the gameplay. This game nails the setting, monster design, buildup, and music, with the best collection of death screens I've seen (outside of its sequels). That being said, lets list the gameplay experiences of each of the monsters, and see if you can understand why this game is bad at horror.
Specimen 2:Hold W
Specimen 3:Hold W
Specimen 4:Hold W
Specimen 5:Hold W
Specimen 6:Look behind you when he laughs
Specimen 7:Hold W
Old Specimen 8:Hold W
New Specimen 8:Ok, this one is pretty cool, but after you realize what is happening, all you have to do is keep close to it around walls
Specimen 9:TAKE THE DEAD TO TAKE THE DEAD TO TAKE THE DEAD TO TAKE THE DEAD TO
Specimen 10:Escort Mission
Specimen 11:Hold W
Specimen 12:The easiest game of hide and seek ever, then hold W
Specimen 13:Ok this one is actually pretty good. Technically, you could just camp until your HP is recovered, but at that point, I have to ask you why you are taking fun out of the games you play. Do you use cheats to give yourself diamonds in Minecraft? Do you look up spoilers for shows you watch? Do you play Basketball without an opposing team?
Specimen 9 (again):I don't think I've ever seen anyone get hit by this boss
As you can see, this game is very easy, and that is bad when you want people to be scared. This game nails every other aspect, but its really bad when the least scary part of your game is the actual chase.
