Saiko is so menacing. It is almost like you can tell her intentions as to why she wants you dead, which is probably to stuff you and become a 1. Toy 2. Stabby Doll 3. So she can be with (Player) for ever. Also, I love the way the AI works. She is checking the rooms, not knowing where you are, constantly taunting you. She is searching endlessly listening and watching for you.
It is amazing how they made a game 10x better than Yandere Sim, which has been in development since 2011... YANDERE SIMULATOR IS AS OLD AS SKYRIM! I know it is a much larger game, but the excuses have gone too far, and he is doing illegal things like making merch of placeholders. Point is, it is obvious they tried to make something good, unlike Yandere Dev who just started putting shit from his pants onto a screen and saying "good". The game is well done, buggy but at the buggy sweetspot, terrifying, and it obviously is is great enough for Markiplier to play it AND get scared, even if it is for a 3 Random Games episode.
