So, here's a simple trick that can help you play Yandere Simulator more effectively. First, you need to rank up in the chemistry subject on Mondays and Tuesdays. Then, on Wednesday, enter the chemistry lab and take the poison. Go to the roof and poison the meals of the purple-haired girl while she's admiring Senpai. Easy enough, right?
But what if Senpai isn't the first one to notice the poisoned girl? What if someone else sees her first? Also, did you know that if you kill more than three people and your sanity is low, your sanity will become normal again when you see Senpai?
Now, let's talk about some interesting bugs in the game. First, if you poison a girl and bring her corpse to the incinerator, there's still blood showing. Another bug is related to the scenario where you poison the purple-haired girl, and a student follows you to the body before Senpai notices. The student is supposed to report it to the teacher, but sometimes they don't, causing you not to be able to go to classes. You could try fast-forwarding to the end of the day to see if it fixes the issue, but sometimes it persists into the next day.
And here's another bug: If you poison a girl and take her away from the school building, she may appear bloody when you go outside with her. Quite the visual glitch, right?
But let's not forget about the fun interactions in the game. For example, you can ask a girl with cyan hair to follow you using the favor mechanic. In my playthrough, she saw the dead body and exclaimed, “Oh my god, is that a dead body?” Did you remember to get the item from the nurse's drawer? Or the medicine from the desk drawer? These tools can be quite useful.
On a darker note, Ayano's childhood was quite unique. Her mother, Ryoba, subtly taught her how to get away with murder. Quite an interesting backstory, wouldn't you say?
