Uncheck the no outlines cheat codes after you enable it to prevent the game from crashing.
The game was 60fps but you need overclock the new 3ds(not stable in some stages with many enemies).
Only thing drive me crazy is all these new horror games nowadays is its so dark, all time. I can't even play them. I understand they trying to create spooky but be creative a little, not just darkness with pop out scare scenes.
